Dual-interface radar data recorder

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.
