Abstract

The invention provides a method capable of quickly identifying a target and a burst height and a detection device. The method comprises the following steps: S1, the picture where the target is located is introduced and reflection coefficient corresponding to the target is selected; s2, a receiving antenna receives a target echo signal and transmits the target echo signal to a signal initial processing module; s3, after echo signals are primarily processed, the echo signals are transmitted to a signal reprocessing module; s4, the signal reprocessing module processes the signals again and transmits the signals to the FPGA chip; s5, the FPGA chip performs result comparison according to the signal. The detection device mainly comprises a camera, a signal receiver, an FPGA chip comprising a target identification sub-module, and a control and output module. The target identification sub-module comprises a target identification model constructed based on a YOLOv5 algorithm. The method solves the problem that burst height judgment cannot be accurate due to the fact that reflection coefficients of different targets are different, and has the advantages of rapidly recognizing the targets and dynamically adjusting the reflection coefficients.

Description

Technical field[0001]The present invention relates to the field of radio receiving detection techniques, and in particular, to a method and detection device capable of rapidly identifying a target, a high blow.Background technique[0002]Proximity Fuse is a letter of existence, distance and direction of the target characteristics or environmental characteristics. Non-contact fuse is called. Near-fried tribunies can be used in killing bombs, fake bomb, killing / broken armor, burst bomb, tapping, taking the bomb, etc., can also be used in combustion bombs, smoky bombs, etc. Special bombs . Approached to killing bombs, fake bomb, killing / broken armup, and the overall performance increase is very obvious. Retrieving trust is a letter that best reflects the advancement of ammunition, is a letter that is most likely to achieve ammunition lifting insurance and inflammation control intelligence.[0003]Different types of near-fried fleemeters, the scope of the fire control system is slightly...
