摘　　要：毫米波超近程线性调频连续波(LFMCW)雷达运动目标参数估计新方法,可以在加速度运动目标环境中有效估计出目标的加速度、速度和距离参数。该方法能够对加速度运动目标多普勒信号进行加速度补偿,解决目标多普勒频谱畸变现象和LFMCW雷达固有的距离速度耦合现象,达到改善加速度运动目标的检测性能和提高参数估计精度目的,且算法稳健,运算量小。算法通过仿真分析,评估了加速度运动补偿前后的效果,证明了算法的有效性。该方法可用于针对毫米波超近程LFMCW雷达信号处理快速、准确的参数估计。Aiming at the Doppler spectrum aberration and range-velocity coupling phenomena in accelerated moving environment for millimeter-wave short-range linear FMCW radar, a novel method is presented, which can estimate the target＇s acceleration, velocity and range effectively. The method can also be used for compensating the Doppler signal with the estimated acceleration, solving Doppler aberration and range-velocity coupling and improving the detection performance and parameter estimation Precision of the accelerated targets. The method has less computation, and the method arithmetic is solidity. The method can be used in the signal processing of fast and precise parameter estimation for millimeter-wave short-range linear FMCW radar.
