The Application of the Target Tracking of Monopulse Tracking Radar

Monopulse tracking radar is the most widely used of a modern tracking radar , which uses the and difference beam angle measurement with high angle measurement accuracy , the information in a very short period of time to obtain the target angle error . Monopulse tracking radar ranging , speed and angle measurement performance and promote the use of digital signal processing technology has become the core of the radar signal processing . In this paper, a monopulse tracking radar signal processor as the background , the first distance, speed and angle of the monopulse tracking radar tracking measurement principle to make elaborate . And then discussed in the above discussed on the basis of basic linear filtering of radar data processing algorithms including the Kalman filter algorithm , described in detail the process of Kalman filter algorithm , the algorithm is given recursive block diagram , and a brief analysis of the Kalman filtering algorithm should pay attention to. Finally, the actual test of the external field on the basis of the collected data , a monopulse tracking radar tracking performance through simulation analysis of the test data to make estimates and Kalman filter algorithm simulation data . Simulation results show the good performance of the radar tracking Kalman filtering effect , the uniform of the target changes .
