摘要

针对由一个发射机和两个空间分离的接收机组成的雷达系统，提出了一种超宽带(UWB)信号的高速处理算法，用于检测慢速运动目标。该算法允许我们在较高的信噪比下，以信号的峰值因子作为剔除雷达图像影响线的标准，对观测系统的信号进行连续处理，并以用户友好的形式显示数据。在局部探测过程中，假设目标位移较小，通过从每个接收点的信号中减去观测过程的交替采样，实时实现信号积累和干扰吸收。通过对目标相对于每个接收器的运动路径进行多项式近似，保证了信号从目标反射到接收点的延迟差异的连续测量。

UWB Technology for Detecting Alive People Behind Optically Opaque Obstacles

A high-speed processing algorithm for ultrawideband (UWB) signals has been developed to detect slow moving objects for the radar system consisting of a transmitter and two spatially separated receivers. The algorithm allows us at relatively high signal-to-noise ratio to use the peak-factor of signals as a criterion for rejecting the affected lines of the radar image and to carry out the continuous processing of signals of the observing system with displaying the data in a user-friendly form. Signal accumulation and interference absorption is realized in real time by subtracting the alternating samples of the observed process from signals of each receiving point assuming the small shift of the object during the local sounding. Continuous measurements of differences of the delays of a signal reflected from the target to the receiving points are ensured by the polynomial approximation of the object's motion path relative to each of the receivers.
