Theory
This lab is configured for one Tx antenna and one Rx antenna and utilizes the Zoom FFT technique which entails two steps. The first step involves taking a 1D coarse FFT in order to search for a peak. The second step involves a second zoom-in fft which analyzes the a portion of the peak spectrum at much higher resolution.

从文档的原理介绍看看，先是用一次fft找到peak，然后再对peak做更细致的fft以获得更高的距离精度。
