针对对称三角线性调频连续波（STLFMCW）雷达体制，分析了目标运动对回波信号的影响，提出了基于距离像峰值偏移估计和脉组相位差分的径向运动参数估计方法，较好地解决了目标运动的补偿问题。仿真结果表明，该方法估计精度高，抗噪性能好，运算量低，便于系统实时处理。

The effect on echo of a moving target is analysed for symmetrical triangular linear frequency modulation continuous wave(STLFMCW) radar.A novel method based on burst-to burst phase difference principle combined with the estimation of target radial motion parameter is presented.Using this method,motion compensation problems are solved well.Simulation results show that this method can perform accurate estimation with low computation volume and good anti-noise performance to be suitable for real-time processing.
