Moving Target Hough Detector in Randomly Arriving Impulse Interference
نویسنده
چکیده
The Hough detector is investigated with three types of Constant False Alarm Rate (CFAR) processors – an Adaptive censoring Post detection Integration (API CFAR) processor, a Binary Integration (BI CFAR) processor and an Excision with Binary Integration (EXC CFAR BI) processor in the presence of randomly arriving impulse interference. The detection probability and the average detection threshold of a Hough detector are studied with these three types of CFAR processors. The experimental results are obtained by numerical analysis. The target echo signal fluctuates according to a Swerling II case model in the randomly arriving impulse interference with a Poisson distribution of the probability of appearance and a Rayleigh distribution of the amplitudes. The research work is performed in MATLAB computational environment. The analytical results obtained for Hough detector can be used in both radar and communication receiver networks.

In this chapter, several advanced detection algorithms for Track-Before-Detect (TBD) procedures using the Hough Transform (HT) are proposed and studied. The detection algorithms are based on the scheme described in (Carlson et al., 1994) to use the Hough transform for simultaneous target detection and trajectory estimation. The concept described in (Carlson et al., 1994) accepts that a target m...
