Multi-Frequency Radar Tracking System Algorithm Research And DSP Implement

Multi-Frequency CW Radar is a type of high performance radar.It is srructure-simple,accurate and easily adaptable to the adoption of digital signal proecssingtechnology.It can be widely used in launching site measurement and other related fields.Based on the Multi-Frequency CW Radar Terminal System,this paper mainly discusses the velocity-measurement,angle-measurement and range-measurement of the Tracking System.In the end, algorithms are programmed on DSP.In the 'velocity-measurement' section,kinds of general methods which often used in estimating Doppler frequency are compared to each other.According to the compared result and the system requirement, Periodical Spectrum Estimation is choosed.In the 'angle-measurement' section,angle measurement method based on digital spectrum is discussed,and some factors which can impact the measurement performance are also analysised in detail.In the end of the section,the paper introduce the range-measurement principle in short.In the 'DSP programming' section,the system requirement is mainly discussed.New generation float DSP ADSP21161 is choosed as the real-time processing chip.Based on ADSP21161,The signal processing board of the Tracking Control System is designed.The section put emphasized on the software design.The last section sum up the contant of the thesis and point out the questions which should be resolved in the future.
