LFMCW雷达距离分辨力的分析及改善
Analysis and improvement of LFMCW radar's range resolution
摘要
Abstract
In order to improve the range resolution of (LFMCW) radar, a cross-eight section open-loop method to the relationship among LFMCW radar's actual range Linear Frequency Modulation Continuous Wave is proposed to correct the FM linearity. According resolution, bandwidth and frequency resolution, a 2 GHz large bandwidth and 4096-point FFT operation are selected. The irregular region of beat signal is avoided when computing the frequency and the sampling data is intercepted from the regular region. Simulation and experiments show that the above treatments have brought some improvement to the radar's range resolution.关键词
