| Abstract: | Higher performance is required for a receiver of modem radar system. Digital receiver technology is an effective imple-mentation method of high accuracy and wide band radar receiving systems. The theory and technology of digital receiver are intro-duced in this paper. The digital down conversion, Number Controlled Oscillator (NCO), Cascade integrator comb (CIC) filter and decimation are discussed. An example for implementing a digital receiver based on FPGA is presented. The analysis and simu-lation are made and the test results are provided. |
| Keywords: | digital receiver FPGA digital down conversion NCO CIC filter |
