Radar large target simulation system and method based on real-time dynamic convolution

Abstract

The application provides a radar large target simulation system and method based on real-time dynamic convolution, wherein the system is controlled by a master control unit; the master control unit is used for completing the control of a work flow and a mode, the configuration and issuing of parameters, the receiving and display of a work state, the display and analysis of waveform data, the issuing and management of a playback file, and has the ability of receiving remote control; a medium frequency unit is used for completing the analog-digital conversion of a channel signal and the modulation of a target echo signal; a micro wave unit is connected with the medium frequency unit and is used for completing the up-conversion and down-conversion of a radio frequency signal, power modulation and detection output functions. The application can complete the echo simulation of a large body target by only performing real-time dynamic convolution on the target characteristics in the radial distance dimension, and can be completed by consuming a small amount of FPGA multiplier resources. The strong scattering points are divided according to the radial distance dimension, and the convolution position is flexibly adjusted, so as to reduce the actual convolution point number and save the multiplier resources.
