Abstract

The invention relates to a radar signal processing system. A FPGA preprocessing module is used for preprocessing radar information. A DSP processing array is used for processing the preprocessed radar information. A multimode loading module is used for loading different preprocessing programs to the FPGA preprocessing module according to different instructions. A power consumption management module is used for managing the power consumption of the system. A state monitoring module is used for transmitting the state information of the system to the master control unit of the radar system and receiving the feedback information of the master control unit. The system uses FPGA + DSP hardware processing architecture, gives scope to the characteristics of the FPGA and the DSP, completes real-time operation of a complex radar information processing algorithm, can achieve the maximum cost-effectiveness of intensive information processing, and solve the memory bottlenecks of the DSP and FPGA by using DDR3 and high-speed SRAM technology.

Description

technical field [0001] The invention belongs to the field of digital signal processing, and relates to a radar signal processing system, in particular to a signal processing system for a C6678 of TI Company and a high-performance FPGA-V6 chip of Xilinx Company as main processors. Background technique [0002] With the introduction of complex radar signal processing algorithms, higher requirements are placed on the computing power and real-time performance of the hardware system. Currently, using parallel processing technology is an important way to improve processing performance. In order to meet the ever-increasing demands of signal processing for processing performance, multi-processor parallel cooperative processing is an effective method to improve system processing capability.
