The Equipment Design For Demonstrating Radar Principle

Since the 2nd World War, the radar has gotten on the stage in history. In the last dozens of years, the technique and performance of radar has been becoming great. Detecting speed, detecting distance and detecting angle are the basic functions for radar.This dissertation is studied the detecting distance radar based on ultrasonic pulse and the detecting speed radar based on continuity electromagnetic wave, using the theories of the detecting distance and the detecting speed of radar. It is in order to manufacture a suited experiment equipment based on the theory of the radar in the experiment of undergraduate, making undergraduate understand the basic theory of radar visibly.The core of the radar system about detecting distance and signal processing is 16 bit MCS-56F805, which is DSP produced by Motorola Company. DSP56F805 samples the ultrasonic pulse coming back from the target, then measures the distance and shows it on LED.TMS320VC5509A is accomplished the detecting speed and the main control of the radar system, is 16 fixed DSP with high performance and low power produced by TI company.DSP5509A samples the wave coming from T/R module, then measures the target's speed and send this information to the assistant control chip - P89V51 based on boost C51 core MCS produced by Philips company, which controls the LCD.The modularization theory is adopted during the design of the software and the debugging, so the work of debugging is predigested as well as easier to the maintenance and upgrade of the programs.In this dissertation, the design of the hardware and software of the detecting radar based on the ultrasonic pulse are completed, including the debugging on the system and the hardware of CW radar.
