Description

Technical Field

[0001] This invention relates to the field of integrated application technology of multifunctional systems, and more specifically, to a method, medium, and device for precise signal delivery based on situational awareness. Background Technology

[0002] Existing multifunctional systems can acquire different characteristics of a target through various means. For example... Figure 1 In the integrated system application shown, which has detection, jamming and reconnaissance functions, the airborne detection system detects targets, discovers protected airborne targets, and provides airborne target early warning. When the integrated system is protecting the protected airborne targets, it obtains the positions of the protected airborne targets and the airborne detection system through detection, and obtains the detection signal parameters of the airborne detection system through reconnaissance. When the protected airborne targets enter the area that needs to be protected, it transmits a suppression signal in the direction of the airborne detection system to disrupt the airborne detection system's ability to detect and discover the protected airborne targets.

[0003] In existing technologies, continuous signals are typically used to suppress the echo signals of the protected air targets, thus preventing the airborne detection system from detecting the protected air targets.

[0004] The signal timing relationship in existing technologies is as follows: Figure 2 As shown, the integrated system opens a short window to detect the airborne detection system and the protected airborne target, and obtains the timing and direction of the suppression signal transmission; it also opens a short window to reconnoiter the detection signal of the airborne detection system and supports the selection of suppression signal style; at other times, it transmits continuous signals to continuously suppress the target echo signal received by the airborne detection system, so that the protected airborne target cannot be detected.

[0005] The signal timing methods of existing technologies are relatively Figure 1 The integrated system application shown has problems such as low system utilization efficiency and waste of resources. Figure 2 The transmission of suppression signals takes up most of the time, but the actual application only requires covering the echo signals of airborne detection targets. The remaining time can be allocated to detection or reconnaissance to obtain more information on the location of airborne targets and electromagnetic situational awareness. The continuous suppression using continuous signals does not utilize the time that is staggered with the echo signals of early warning targets, thus wasting resources. Summary of the Invention

[0006] The present invention aims to provide a method, medium, and device for precise signal delivery based on situational awareness, in order to solve the above-mentioned problems. By acquiring situational awareness information such as electromagnetic and position information of the target through the reconnaissance and detection functions of the integrated system, the suppression signal can be precisely delivered, thereby improving the efficiency of the multi-functional integrated system.

[0007] The present invention provides a method for precise signal delivery based on situational awareness, comprising the following steps:

[0008] S1, the integrated system acquires detection signal information from the airborne detection system through electronic reconnaissance functions;

[0009] S2, the integrated system obtains spatial location information of the airborne detection system and the protected airborne targets through its detection function;

[0010] S3 generates a signal timing relationship based on the spatial position information of the airborne detection system and the protected airborne target, as well as the detection signal information of the airborne detection system, to achieve precise signal delivery based on situational awareness.

[0011] Furthermore, in step S1, the acquired airborne detection system signal information includes the frequency, bandwidth, pulse width T_pulse, and repetition period T_pri of the airborne detection system signal.

[0012] Furthermore, step S2 includes the following sub-steps:

[0013] S21, the integrated system uses its detection function to detect the distance R1 between the integrated system and the protected air target, as well as the distance R2 between the integrated system and the air detection system, and simultaneously obtains the angle θ between the protected air target and the line connecting the air detection system and the integrated system.

[0014] S22, using the obtained R1, R2 and included angle θ, calculate the distance R3 from the airborne detection system to the protected airborne target based on trigonometric relationships.

[0015] Furthermore, step S3 includes the following sub-steps:

[0016] S31, based on the relationship between the propagation speed of electromagnetic waves in space and the mutual distance R1, R2, and R3, calculate the signal arrival time between the integrated system, the airborne detection system, and the protected airborne target, respectively;

[0017] The time T1 when the signal transmitted by the integrated system arrives at the protected air target, the time T2 when the signal transmitted by the air detection system arrives at the integrated system, and the time T3 when the signal transmitted by the air detection system arrives at the protected air target;

[0018] S32, a model for constructing an airborne detection system where early warning echo signals and suppression signals arrive simultaneously, based on signal arrival time;

[0019] S33 utilizes a model that constructs early warning echo signals and suppression signals that arrive at the airborne detection system simultaneously to generate signal timing relationships, thereby achieving precise signal delivery based on situational awareness.

[0020] Furthermore, in step S31, the signal arrival time between the integrated system, the airborne detection system, and the protected airborne target includes:

[0021] The time T1 when the signal transmitted by the integrated system arrives at the protected air target, the time T2 when the signal transmitted by the air detection system arrives at the integrated system, and the time T3 when the signal transmitted by the air detection system arrives at the protected air target.

[0022] Furthermore, in step S32, constructing a model for the simultaneous arrival of early warning echo signals and suppression signals at the airborne detection system includes:

[0023] Taking the time when the airborne detection system transmits the signal as a reference, the time when the integrated system sends out the suppression signal to the airborne detection system immediately after receiving the signal is 2×T2, and the time when the airborne detection system receives the echo of the protected airborne target is 2×T3. Under normal circumstances, (2×T2)>(2×T3), which does not meet the requirement of simultaneous arrival.

[0024] Based on the repetition period T_pri of the detection signal from the airborne detection system, the integrated system transmits a suppression signal after receiving the signal by delaying the transmission time T_delay. When 2×T2+T_delay=T_pri+2×T3 is satisfied, the suppression signal and the target echo of the next transmission pulse of the airborne detection system arrive at the same time, achieving the suppression effect.

[0025] Furthermore, step S33 includes: integrating the information from the system reconnaissance and detection in steps S1 and S2, calculating relevant parameters, and using the model constructed in step S3 where the early warning echo signal and the suppression signal simultaneously arrive at the airborne detection system, calculating the delayed transmission time T_delay after receiving the signal in real time according to the formula T_delay=T_pri+2×T3-2×T2, with the transmission frequency covering the detection frequency of the airborne detection system and the suppression signal having a duration slightly longer than the detection pulse width, thus realizing the signal timing relationship and achieving precise signal delivery based on situational awareness.

[0026] The present invention also provides a computer terminal storage medium storing computer terminal executable instructions, which are used to execute the above-described method for precise signal delivery based on situational awareness.

[0027] The present invention also provides a computing device, comprising:

[0028] At least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the above-described situational awareness-based precise signal delivery method.

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0030] This invention utilizes situational awareness information obtained from reconnaissance and detection by an integrated system to achieve precise signal delivery in integrated system applications. Compared with existing technologies, the duration of the suppressed signal is shorter, and most of the time can be flexibly allocated to other functions, thereby improving the efficiency of the multi-functional integrated system.

[0031] The specific effects are as follows:

[0032] 1. Improved efficiency of integrated system: Compared with the existing continuous signal suppression method, the signal transmission time occupied by the present invention based on situational awareness can usually be reduced to about 10% to 20% of the original time. The remaining time resources can be flexibly allocated to the detection, reconnaissance and other functions of the integrated system, thereby maximizing the efficiency of system resource utilization.

[0033] 2. Enhanced suppression effect: The duration of the suppression signal is reduced, which decreases the probability of the airborne detection system obtaining accurate samples of the suppression signal in dynamic confrontation with the system, weakens its ability to cancel and suppress, and enhances the suppression effect.

[0034] 3. Improved cost-effectiveness: By adopting the method of this invention, the duration of the suppression signal is shortened, and the power required to achieve the same suppression effect is reduced to 1 / 5 to 1 / 10 of the original. At the same transmission power, the power of the suppression signal can be increased by 5 to 10 times, thus improving the cost-effectiveness of the system. Attached Figure Description

[0043] Example

[0044] This embodiment proposes a method for precise signal delivery based on situational awareness, including the following steps.

[0045] S1, the integrated system acquires detection signal information from the airborne detection system through electronic reconnaissance functions;

[0046] S2, the integrated system obtains spatial location information of the airborne detection system and the protected airborne targets through its detection function;

[0047] S3, based on the spatial position information of the airborne detection system and the protected airborne target, and the detection signal information of the airborne detection system, generates a signal timing relationship to achieve, as follows: Figure 3 The situational awareness-based signal delivery demonstrated improves the efficiency of the multi-functional integrated system.

[0048] like Figure 3 In the signal timing shown, by precisely controlling the signal transmission time, the suppression signal and the early warning echo signal arrive at the airborne detection system simultaneously. When the duration is slightly longer than the duration of the echo signal, the airborne detection system's ability to detect and find the protected airborne target can be disrupted.

[0049] like Figure 4 As shown in the typical application scenario, this embodiment proposes a method for precise signal delivery based on situational awareness, including the following steps:

[0050] The first step is for the integrated system to use electronic reconnaissance capabilities to acquire information on the detection signals from the airborne detection system, including the frequency, bandwidth, pulse width T_pulse, and repetition period T_pri of the airborne detection system signals.

[0051] The second step is that the integrated system uses its detection function to detect the distance R1 between the integrated system and the protected air target, as well as the distance R2 between the integrated system and the air detection system. At the same time, it obtains the angle θ between the protected air target and the line connecting the air detection system and the integrated system.

[0052] The third step is to calculate the distance R3 from the airborne detection system to the protected airborne target based on the obtained R1, R2 and included angle θ, according to the trigonometric relationship.

[0053] The fourth step is to calculate the time T1 when the signal transmitted by the integrated system reaches the protected air target, the time T2 when the signal transmitted by the air detection system reaches the integrated system, and the time T3 when the signal transmitted by the air detection system reaches the protected air target, based on the relationship between the propagation speed of electromagnetic waves in space and the distance between them (R1, R2, R3).

[0054] The fifth step is to construct a model in which the early warning echo signal and the suppression signal arrive at the airborne detection system simultaneously. Taking the transmission time of the airborne detection system as a reference, the time it takes for the suppression signal to reach the airborne detection system immediately after the integrated system receives the signal is 2×T2. The time it takes for the airborne detection system to receive the echo of the protected airborne target is 2×T3. Under normal circumstances, (2×T2)>(2×T3), which does not meet the requirement of simultaneous arrival. Based on the repetition period T_pri of the detection signal obtained from the airborne detection system, the integrated system transmits the suppression signal after receiving the signal by delaying the transmission time T_delay. When 2×T2+T_delay=T_pri+2×T3 is satisfied, the suppression signal and the target echo of the next transmission pulse of the airborne detection system arrive at the same time, achieving the suppression effect.

[0055] The sixth step involves the integrated system detecting and reconnaissance to perceive the target's location and electromagnetic situation in real time, calculating relevant parameters, and calculating the delayed transmission time T_delay after receiving the signal in real time according to the formula T_delay = T_pri + 2 × T3 - 2 × T2 based on the model constructed in the fifth step. The transmission frequency covers the detection frequency of the airborne early warning detection system, and the duration of the suppression signal is slightly longer than the detection pulse width, thus realizing the present invention. Figure 3 The signal timing relationship.

[0056] Figure 5The diagram illustrates an application example of the present invention's situational awareness-based precise signal delivery method in a certain engineering project. Based on situational awareness information, the system precisely delivers suppression signals, transmitting only signals that overlap with the echoes of the protected target. The remaining time, aside from the necessary detection and reconnaissance time, is used flexibly for the system's detection and reconnaissance functions, resulting in better situational awareness and maximizing system resource utilization efficiency. Simultaneously, the system concentrates all available transmission power during the suppression signal transmission period, increasing the suppression power tenfold and achieving a better suppression effect.

[0057] Furthermore, in some embodiments, a computer terminal storage medium is proposed, storing computer terminal executable instructions for executing the situational awareness-based precise signal delivery method described in the preceding embodiments. Examples of computer storage media include magnetic storage media (e.g., floppy disks, hard disks, etc.), optical recording media (e.g., CD-ROMs, DVDs, etc.), or memory such as memory cards, ROMs, or RAMs. The computer storage medium can also be distributed across a network-connected computer system, for example, as an application store.

[0058] Furthermore, in some embodiments, a computing device is proposed, comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the situational awareness-based precise signal delivery method as described in the foregoing embodiments. Examples of computing devices include PCs, tablets, smartphones, or PDAs.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
