Research Of Signal Processing Technique Based General Platform In Some Radar System

The development and some key technologies of radar signal processing with a type of radar system are introduced. And the principle of Digital Beam Forming (DBF) and Adaptive Clutter Cancellation in this radar system, which perform direct signal rejection and multi-path clutter rejection in receiving and detection. Those DBF and Adaptive Clutter Cancellation are presented in general signal processing platform are discussed in detail by this radar system. And DBF function block is optimized with the hardware source of general signal processing platform, which real-data pretreatment and operation of multi-beam-forming calculation are parallel presented. With the help of real data collection and processing, the Adaptive Clutter Cancellation block is mended, and the effect of mended Adaptive Clutter Cancellation function block is given compared with original way, with which the weak echo of moving target can be detected. Finally the engineering realization of Adaptive Clutter Cancellation function block is discussed with general signal processing platform.
