In this paper CA CFAR, excision CFAR, CA CFAR BI, excision CFAR BI and API CFAR processors in strong pulse jamming (PJ) are discussed . We investigate the influence of the scale factor over probability of false alarm and detection probability in strong PJ for one-dimensional CFAR processors. The efficiency of oneand twodimensional CFAR processors by using the average decision threshold (ADT) ap...

In this chapter, we propose to use a GO CFAR processor for PN code acquisition in DS/CDMA systems. We compare the single-dwell scheme without the verification mode using the GO CFAR processor with that using the CA and OS CFAR processors. From the simulation results, we can observe that the DS/CDMA systems with the GO CFAR processor has better performance than those with the CA and OS CFAR proc...

In this paper, we propose a novel algorithm for a CFAR radar detector. The proposed processor is derivated from OS CFAR one and is based on weighting samples taken for the background level estimate. We assume that targets are embedded in a Gaussian noise and fluctuate according to Swerling I model. First, closed form expressions of the probabilities of detection and false alarm are determined a...

Many present spaceborne synthetic aperture radar (SAR) systems are constrained to only two channels for ground moving target indication (GMTI). Along-track interferometry (ATI) technique is currently exploited to detect slowly moving targets and measure their radial velocity and azimuth real position. In this paper, based on the joint probability density function (PDF) of interferogram’s phase ...

A constant false alarm rate (CFAR) target detector in non-homogenous backgrounds is proposed. Based on K-sample Anderson-Darling (AD) tests, the method re-arranges the reference cells by merging homogenous sub-blocks surrounding the cell under test (CUT) into a new reference window to estimate the background statistics. Double partition test, clutter edge refinement and outlier elimination are ...

Reliable radar constant false alarm rate (CFAR) detection is critical in dynamic clutter and jamming scenarios [2]. The existence of heterogeneities in practical operational environments renders the conventional cell averaging CFAR (CA-CFAR) ineffective. Heterogeneities arise due to the presence of multiple targets and clutter edges [3]. Alternative schemes have been developed to address this i...

Herein, a robust constant false alarm rate (CFAR) detector with ordered statistic of sub-reference cells (OSS-CFAR) is proposed in multiple target situations. This can improve background level estimation and reduce computational complexity using cells. The detection performance the OSS-CFAR conventional CFAR detectors situations are investigated compared computer simulations experimental data s...
