摘要

本文概述了利用第二代数字地面电视DVB-T2标准信号发射机作为机会光源的无源相干定位雷达。雷达天线设计为16元相控阵。信号接收和模数转换由18通道接收单元完成。信号处理的主要阶段是通过联合使用中央处理单元和图形处理单元来并行化的。自适应LMS、NLMS和LSL滤波器用于杂波消除。目标检测采用恒虚警率算法。图中显示了车辆、直升机和飞机的探测结果。给出了雷达势特性的估计。

DVB-T2 passive coherent location radar

In this paper, an overview of the passive coherent location radar utilizing transmitter of signals of the second generation digital terrestrial television DVB-T2 standard as an illuminator of opportunity is presented. The radar antenna is designed as an 16-element phased antenna array. The signal reception and analog-to-digital conversion are performed by the 18-channel receiver unit. The main stages of signal processing are parallelized by the combined use of central processing units and graphics processing units. Adaptive LMS, NLMS and LSL filters are used for clutter cancellation. The target detection is accomplished with the aid of Constant False Alarm Rate algorithm. The results of detection of vehicles, helicopters and aircrafts are shown. The estimation of the radar potential characteristics are presented.
