Description

Technical Field

[0002] Terminal self-defense mechanisms for flight platforms against radar-guided weapons are mainly divided into passive and active jamming. Active jamming includes towed decoys and drop-type decoys, both of which employ a reconnaissance-relay jamming system.

With the development of terminal guidance weapons, their radar operating frequency bands have expanded to the millimeter-wave Ka band, and signal patterns increasingly utilize broadband frequency-agile signals. However, existing drop-type active decoy flares are designed based on the X / Ku band, a common frequency band for terminal guidance radars, and their instantaneous operating bandwidth typically does not exceed 1 GHz, rendering existing drop-type active decoys ineffective against them.

[0045] A frequency synthesizer, which is used to provide a local oscillator signal;

[0046] A T / R assembly is connected to the millimeter-wave antenna assembly, and the T / R assembly is used to filter and amplify the millimeter-wave received signal and the millimeter-wave transmitted signal.

[0047] The frequency converter is connected to the T / R component and also to the frequency synthesizer.

[0049] In one embodiment, the launch case includes a main housing 1, a primer device 2, a buffer piston 3, and a front cover 4; a detachable adjustment cover is provided on one side of the main housing 1, the adjustment cover corresponding to the external adjustment interface of the decoy projectile, the main housing 1 is used to accommodate and fix the decoy projectile; the primer device 2 is used to fill the bottom of the main housing 1; the front cover 4 is snap-fitted to the main housing 1.

[0050] In this embodiment, the launch case is a standard 1*2*8 airborne decoy launch case. The launch case includes a main shell 1, a primer device 2, a buffer piston 3, and a front cover 4. The main shell 1 is used to accommodate and fix the decoy projectile. A detachable adjustment cover is provided on one side of the main shell 1, which corresponds to the external adjustment interface of the decoy projectile. The primer device 2 is a standard pyrotechnic explosive, which is filled at the bottom of the main shell 1. When the decoy projectile is filled, it is close to the ignition tube. After the primer device 2 is activated by external control, it explodes and ejects the decoy projectile from the barrel. The buffer piston 3 is made of metal and is adapted to the shape of the front and rear radomes of the decoy projectile. Under high overload during launch, it disperses the impact force to the first cavity 6 of the decoy projectile to avoid the radome being directly stressed. The front cover 4 is connected to the main shell 1 by a snap-fit. The front cover 4 has a rubber gasket inside for sealing and buffering the force.

[0051] This utility model's millimeter-wave broadband throwable active radio frequency decoy munition includes a packaging and storage stage, a launch activation stage, a reconnaissance stage, a jamming stage, and a self-destruct stage during combat use. The packaging and storage stage involves the decoy munition being filled into the launch casing and sealed for transport, storage, and operational readiness. During operational readiness, the decoy munition can be directly mounted on an airborne jamming launcher for immediate launch. The launch activation stage occurs when the airborne jamming launcher receives a system launch command and activates the primer device 2 of the decoy munition's launch casing. The primer device 2 explodes, generating a high-temperature, high-pressure blast wave. The impact force is transmitted sequentially to the decoy munition body and the front cover 4 via the buffer piston 3. The latching connection between the front cover 4 and the main casing 1 of the launch casing is broken, and the decoy munition is ejected from the barrel. The four foldable tail fins 7 rapidly unfold and lock under the action of torsion springs, stabilizing the munition's flight. Simultaneously, the explosion of primer 2 will activate the rear-end ignition tube of the decoy projectile, thereby activating the thermal battery. The thermal battery will then power the decoy projectile system, and the system will complete self-test and initialization configuration. During the reconnaissance phase, after the system completes initialization, it automatically enters the frequency sweep reconnaissance state, performing time-division frequency sweep reconnaissance of the forward and backward reconnaissance airspace and the millimeter-wave Ka band. The instantaneous bandwidth is not less than 4 GHz. During the dwell time of each frequency sweep channel, the millimeter-wave radar signal detected by the millimeter-wave antenna assembly is converted into a broadband received intermediate frequency signal via the T / R channel and down-conversion channel of the radio frequency assembly. This signal is then sent to the high-speed data acquisition and conversion module of the signal processing circuit to complete analog-to-digital conversion. The resulting high-speed digital signal is then digitally stored and processed by the signal processing module. Digital storage is performed in DRFM (Digital Radio Frequency). In the Radio Frequency Memory (DRFM) system, high-speed acquired radar intermediate frequency (IF) signal samples are stored for subsequent jamming signal modulation generation. The reconnaissance processing includes digital channelization, signal detection, parameter measurement, pulse descriptor word (PDW) formation, and signal sorting and identification. Signal parameter measurement includes estimating parameters such as radar signal arrival time (TOA), pulse width (PW), pulse repetition frequency (PRI), and signal amplitude (PA). These parameters are summarized to obtain the pulse descriptor word (PDW), which can be used for signal sorting and identification, thereby guiding the subsequent modulation generation of targeted jamming signals. In the jamming stage, the digital processing circuit modulates and generates targeted digital jamming signals according to the radar signal characteristics acquired in the reconnaissance stage and an adaptive jamming strategy. This digital jamming signal is converted from digital to analog and sent to the radio frequency transmission channel. After up-conversion and filtering amplification, it is transmitted by the antenna. In the DRFM system, the jamming signal modulation generation directly uses the acquired and stored original radar signal samples, combined with the reconnaissance radar signal characteristics, and generates coherent jamming signals with good deception or suppression characteristics through various means such as dense replication, time delay modulation, Doppler modulation, RCS modulation, and noise modulation.The self-destruct phase, or millimeter-wave broadband throwable active radio frequency decoy munition's self-destruct phase, involves automatically erasing the program and data from the processing chip after being launched, powered on, and operating for a certain period. Since the decoy munition is consumable and non-recoverable, this soft self-destruction ensures that the decoy munition, once launched, will not cause data or technology leakage to the user. This utility model's millimeter-wave broadband throwable active radio frequency decoy munition features detachable debugging covers on both the launch casing and the decoy body. Underneath the debugging cover are the system's external power supply and debugging interfaces. Therefore, the decoy munition can be connected to a loading cable while loaded and without activating the thermal battery, allowing for software program loading, upgrades, and debugging tests via external DC power and communication.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
