Optimized design and performance analysis of small FMCW radar

Abstract： Small size, low power consumption and low probability of intercept are the characteristics of frequency modulation continuous wave(FMCW) radar. It is widely used in vehicle navigation radar, low probability of intercept radar and so on. In this paper, the system draws on the design of the MIT coffee can radar, a small S-BAND FMCW radar system is developed which draws on the design of the MIT coffee can radar and uses the modularized integrated microwave device. The system designs simple array antenna to increase the echo intensity, adjusts electronic circuit boards to enhance system stability, improves audio interface to make the system more widely used and uses Range Doppler(RD) algorithm to measure target velocity. Furthermore, a modified RD imaging algorithm was implemented to the original stop-and-go static model to compensate for the effect of Doppler stretching on synthetic aperture radar(SAR) imaging during motion. The simulation and experiment results show that the system is reasonable and reliable.
