[Abstract]:Distributed wall penetrating radar emits electromagnetic waves from multiple radars, and detects, tracks, locates and imagines the targets behind the walls from multiple angles of view.The distributed radar system in this paper is based on two radar equipments, one transmitting antenna and two receiving antennas.Compared with single view radar, distributed radar system improves the surveillance of hidden targets through cooperative signals, and provides important decision information for anti-terrorism, public security enforcement, military operations and other fields.Aiming at the hardware and software design requirements of distributed radar system, this paper studies the data signal conditioning circuit, data acquisition and preprocessing, step frequency control, power supply circuit, data transmission protocol, signal processing and display control, etc.Finally, the design and implementation of data acquisition and control module, signal processing and display control module are completed, and the specific work is described as follows: 1.Based on the detection and positioning principle of distributed penetrating wall radar, the function and index requirements of each sub-module of the system are analyzed, and the indexes of data acquisition and control module and signal processing and display control module are obtained.According to the index requirement of data acquisition and control module, the hardware and program design of data acquisition and control module is realized, which includes chip selection, hardware circuit design, PCB making and FPGA programming and debugging.Hardware circuit and program control joint debugging. 3.According to the index requirement of signal processing and display control module, the design of signal processing and display control host computer is realized, which mainly includes: WiFi creation and data receiving, upper computer window design, algorithm transplantation, data cache technology,Multithreading technology to complete signal processing and display. 4.The joint debugging of hardware and software is realized, and the whole experiment of the system is carried out, including closed loop experiment and field experiment.The stability of the distributed radar system is tested by closed-loop experiments, and the joint positioning results of the distributed radar system are finally displayed through the field experiments.
