摘要
分析了毫米波雷达阶跳频信号参数以及复杂目标运动对该信号合成目标一维距离像的影响 ,研究了三角波调制下运动速度参数估计方法。仿真表明 ,该方法具有较高的测速精度和较好的抗噪声性能 ,在ADSP2 10 6 2信号处理板上运行时间为 1.2ms。
The parameters of mmW radar stepped-frequency signal and effect of distributed target motion on one-dimensional range profile are analyzed. The method for estimating motion parameter is studied in triangle waveform modulation. The simulating results shows that this method can be used to measure velocity accurately with a better anti-noise performance,its execution time is 1.2ms on ADSP21062 signal processing board.
