摘要
线性调频连续波雷达在理论上具有很高的测距精度，然而其实际系统通常是通过数字信号处理的方法，在其回波功率谱或距离谱上获取其距离信息的，因而受到采样与处理字长的限制，使得其实际测距精度与其距离分辨力处于同一数量级。为此，根据线性调频连续波雷达回波功率谱的特点，提出了一种最大值估值算法。在计算量增加不多的情况下，可以大大提高其实际的测距精度，以满足高精度测距的实际需要。
Abstract The linear frequency modulation continuous wave (LFMCW) radar has high theoretical range precision. But because it acquires the range imformation from its power spectrum through digital signal processing which is limited by the data length, its practical system has lower practical range precision approximating to its range resolution. This paper presents an algorithm to estimate maximum which can obtain higher practical range precision of LFMCW radar and add less computation.
