Dual-interface radar data recorder

Abstract

The invention discloses a dual-interface radar data recorder, which consists of a digital signal processor (DSP) main control module, a field programmable gate array (FPGA) interface control module, an analogue to digital converter (ADC) data acquisition module, a synchronous dynamic random access memory (SDRAM) data cache unit, a network interface chip, a solid integrated development environment (IDE) hard disc and a power supply chip. The connection relationship of the elements is that: the SDRAM data cache unit is connected with the DSP main control module for data caching; the DSP main control module and the ADC data acquisition module are both connected with the FPGA interface control module through buses to exchange data; the FPGA interface control module controls the solid IDE hard disc and the network interface chip to complete data record; and the power supply chip is responsible for supplying voltage required by the whole system. The recorder system is integrated on a printed circuit board (PCB) and conducts dual-interface functions by the coding of a DSP and an FPGA, so the use of specific chips is reduced, the area of the PCB area is reduced and the weight of the system is lightened; and the recorder has the advantages of flexible use and easy modification. The dual-interface radar data recorder has a practical value and a wide application prospect in the technical field of communication control.

Description

(1) Technical field: [0001] The invention relates to a dual-interface radar data recorder. It belongs to the technical field of communication control. (two) background technology: [0002] With the development of ultra-wideband radar technology and software radio, the waveform of radar signals is becoming more and more complex. Only by analyzing and researching the echoes of radar targets in actual situations can the correctness and accuracy of the entire radar signal processing system be guaranteed. stability. Radar echoes will generate a huge amount of data after being processed by the RF front-end and receiving intermediate frequency. In order to preserve the data completely, the recording equipment must be able to track and record the signal in each radar echo pulse continuously and for a long time. Data processing and analysis after the test. Therefore, the data recording equipment plays a very important role in the development and experiment process of the radar see...
