摘要

本文分析了一种具有非相干积分的CMAP-CFAR(杂波映射恒定虚警率)检测器。复包络的预检测器统计量假设为高斯分布。考虑了一个转向II型目标波动模型,并假设入射脉冲是独立的。确定了检测概率和虚警概率的封闭表达式。另一方面,我们提出了一种利用德州仪器DSP TMS320C4x进行后集成的CMAP-CFAR探测器的实时实现。

Analysis and Real Time Implementation of a Clutter Map CFAR Detector with Noncoherent Integration
In this paper, we analysis a CMAP-CFAR (Clutter Map Constant False Alarm Rate) detector with noncoherent integration. The predetector statistics of the complex envelope are assumed Gaussian. A Swerling II target fluctuation model is considered and the incoming pulses are assumed independent. Closed form expressions of the probability of detection and the probability of false alarm are determined. On another hand, we propose a real time implementation of CMAP-CFAR detector with post integration using Texas Instrument DSP TMS320C4x.
