System Implementation And Study Of Realtime Target Detecting And Tracking In The Presense Of Strong Sea Clutter

The coherent integration technique is widely used in radar targets detection. Using this technique can improve the detection probability. In a signal processor, of Anti-warship Missile Active Radar Seeker, we use this method for targets detecting and tracking. The paper consists of the following parts:Firstly, some general models of Radar sea clutter and K-Distributed radar sea clutter were analyzed. The simulation method of K-Distributed radar sea clutter was discussed in details.Secondly, some main algorithms in the presence of strong sea clutter were studied based on the model of K-Distributed Radar Sea Clutter. A new method that can improve precision and stabilization of angle tracking was given.Finally, the design of radar signal processor based on advanced ADSP-21161 was introduced, including hardware and software. And the software developing technology of ADSP-21161, especially with the method of developing cluster multi-processor system, was generalized.
