Abstract

The invention provides a multi-functional radar signal processing plate which comprises a power module, two digital signal processor (DSP) processing nodes, two field programmable gate array (FPGA) processing nodes, two complex programmable logic device (CPLD) modules, three high-speed analog to digital converter (ADC) modules, a high-speed digital to analog converter (DAC) module, a low-voltage differential signaling (LVDS) data collecting output module, two low-speed ADC modules, two low-speed DAC modules and two separated synchronous serial modules. The processing plate is achieved by adopting a high-performance DSP and a Xilinx high-performance FPGA and has the advantages of being good in processing capacity and high in integration of chips with various functions and the like.

Description

technical field [0001] The invention relates to a multifunctional radar signal processing board, which belongs to the field of radar real-time signal processing and related technologies. Background technique [0002] Radar real-time signal processing boards are mainly used in radar signal processing systems, and generally require high-speed multi-channel data acquisition functions, computing-intensive real-time signal processing functions, and dedicated external interface functions. However, most of the current radar real-time signal processing boards have low sampling rate, small computing power and buffer capacity, and the integration of various functional chips is not rich enough to complete the high data rate and computationally intensive radar signal processing tasks. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the existing radar real-time signal processing boards that the processing capability is not stro...
