Radar If Digital Receiver Developed

The Radar Medium Frequency Receiver employ digital signal process algorithm, makes use of flexible digital chips, such as CPLD, FPGA & special DSP. It take on the advantage of small cubage, low weight, cheapness, simple configuration, modularization. And it takes on the all advantage of digitalization. Digitalization is current trend of communication and Radar development. The traditional analog receiver is now replaced by digital receiver gradually. So it has take on a wide foreground.The theory basis for Medium Frequency Receive includes sample theory, the signal's orthodoxy transform theory, multi-rate digital signal processing theory and signal's modulation and demodulation theory. It's hardware platform is current advanced ADC, special or customized chips. And it employ current efficient digital signal process algorithm.The purpose of this article is to introduce the realization of Medium Frequency Receive for BPSK pulse compress Radar. And it includes the realization of constant false alarm rate (CFAR) process. The main content of this article includes:(1) The introduction of Radar Medium Frequency Receiver;(2) The introduction of medium frequency receiver theory;(3) The simulation for Medium Frequency Receive of BPSK pulse compress Radar;(4) The hardware realization for Medium Frequency Receive of BPSK pulse compress Radar.
