Abstract

The invention provides a radar intermediate-frequency receiving and signal processing board based on TM320C6678. The board comprises a power supply module, two DSP (Digital Signal Processor) processing nodes, an FPGA (Field Programmable Gate Array) processing node, three high-speed ADC (Analog to Digital Converter) modules, a high-speed DAC (Digital to Analog Converter) module, an LVDS (Low Voltage Differential Signaling) data acquisition output module, three low-speed ADC modules, two low-speed DAC modules, two isolated synchronous serial port modules and two FLASH modules. The processing board adopts a high-performance eight-core DSP and Xilinx high-performance FPGA, so that the board has the advantages that the processing capacity is high and the integration level of various functional chips is high.

Description

technical field [0001] The invention relates to a radar intermediate frequency receiving and signal processing board based on TM320C6678, which belongs to the field of radar real-time signal processing and related technical fields. Background technique [0002] Radar signal processing boards are mainly used in radar signal processing systems, and generally require high-speed multi-channel data acquisition functions, computationally intensive real-time signal processing functions, and dedicated external interface functions. However, most of the current radar real-time signal processing boards have poor computing power, low sampling rate, and small buffer capacity. The integration of various functional chips is not rich enough, and the interconnection capability of the board is poor. It is difficult to complete high data rate and computing-intensive radar. Signal processing tasks. Contents of the invention [0003] The purpose of the present invention is to overcome the sho...
