Problems solved by technology

[0003] However, for targets with different reflection coefficients, due to the uncertainty of the echo intensity, it is difficult to guarantee the consistency of the output height judgment of the ultra-wideband radio proximity detector based on the existing scheme. Affected by different external factors, etc., it is easy to cause deviations in the judgment of bombing height information, thus affecting the accuracy of bombing height information and the judgment of bombing height consistency

Embodiment 1

[0036] Such as figure 1 As shown, a method for judging the consistency of target explosion height based on radio proximity detection technology includes the following steps:

[0037] S1: Before the actual explosion height detection, set and divide the distance and position of the detection block according to the detection distance between the target and the radio receiving switchboard, and set the radio signal extension at the distance and position set by each detection block. The flying height of the signal extension unit is consistent with the level of the radio receiving switchboard;

[0038] Wherein, the radio receiving switchboard is specifically a radio signal receiver and an information processor mainly composed of an ASIC chip, and the information processor also includes storage, power supply and other conventional components necessary for processor formation, and is equipped with a display for display; The radio signal extension includes the unmanned aerial vehicle a...

Embodiment 2

[0055] This embodiment is basically the same as the embodiment, except that the radio transmitter transmits a chirp signal, specifically:

[0056]

[0057] Among them, S(t) represents the chirp signal; t represents the time variable; j represents the imaginary number, j 2 =-1;f 0 is the carrier frequency; k is the chirp slope; T is the pulse width; the above-mentioned chirp signal can effectively enhance the anti-jamming ability and enhance the ability to find the target at the same time.

Abstract

The invention discloses a method for judging the consistency of target bombing height based on radio proximity detection technology, comprising the following steps: S1: setting each radio signal extension; S2: each radio signal extension transmitting and receiving radio signals, and reflecting the The coefficient estimation module estimates the reflection coefficient of the target; S3: Use the baseband dynamic gain control module to process the signal, and then use the signal processing module to process the signal and transmit it to the radio receiving switchboard; S4: The radio receiving switchboard receives the echo signals of each baseband target, and passes the ASIC The chip calculates the explosion height information; S5: Use the data integration and comparison module of the ASIC chip to jointly compare each explosion height information, eliminate the information with excessive deviation and judge whether the target explosion height is consistent. The invention utilizes multi-angle transmitting radios to detect targets, and then jointly calculates and compares each piece of information, thereby improving the accuracy of judging consistency.

Description

technical field [0001] The invention relates to the technical field of detonation control, in particular to a method for judging the consistency of target explosion height based on radio proximity detection technology. Background technique [0002] Due to the characteristics of high detection accuracy, good signal concealment, strong anti-interference ability, and low power consumption, the ultra-wideband radio proximity detector has been applied in many proximity fuze platforms, and is further used for high-precision radio explosion height detection ; At present, the existing ultra-wideband radio proximity detector receiver can achieve accurate and consistent judgment of the height of a specific target through the timing control of the received sampling pulse and the hard decision technology based on fixed gain. [0003] However, for targets with different reflection coefficients, due to the uncertainty of the echo intensity, it is difficult to guarantee the consistency of ...
