Research Of A Monopulse Precision Instrumentation Radar MTD Ranging Based On DSP

The paper discusses mainly one kind of MTD range tracking measuring technique of the monopulse precision tracking instrumentation radar in terms of the radar being developed by our institute. It introduces the engineering technical indicators, the structure and the operation principle of the ranging system. The main technical indicators of the ranging system are analysed and calculated theoretically based on the given practical example, the tracking performance of the range loop, the method of the frequency ambiguity resolution and the correct of the FFT frequency estimation are all simulated and analysed. Additionally, the working principle of the normal monopulse ranging technique, vernier ranging technique and windband ranging technique are described.The paper first describes the monopulse pricision tracking instrumentation radar technique, digital signal processor technique and the development of the radar range tracking and measuring technique. Then the typical engineering technical indicators of the normal monopulse precise ranging system are given based on the practical example. The structure and the operation principle of the ranging system are also introduced. The basic principles and the implementation approachs of the vernier ranging technique and windband ranging technique are described. Afterwards the paper discusses one kind of technique of the monopulse precision tracking instrumentation radar ranging system. At last, it gives one engineering design example of the MTD tracking and measuring system based on the DSP platform.
