In this paper different CFAR detectors for detection of multiple targets for UWB radar system will be described and their outputs compared. The cell averaging CFAR (CA-CFAR) cell averaging with greatest of (CAGO-CFAR), ordered statistics CFAR (OS-CFAR), clutter map CFAR (CMCFAR) and cell averaging CFAR assumed for gamma distributed clutter will be represented. The properties of all detectors wi...

CFAR (Constant False Alarm Rate) detectors were designed and evaluated in non-homogeneous DVB-T (Digital Video Broadcasting-Terrestrial) passive radar scenarios. The CA-CFAR (Cell-Averaged CFAR) is the most widespread incoherent CFAR technique. CA-CFAR detector is optimal under the assumption of homogeneous interference, but CA-CFAR performance is degraded when this assumption is not fulfilled....

In this paper, a new radar constant false alarm rate detector to perform adaptive threshold target detection in presence of interfering targets is proposed. The proposed CFAR detector, referred to as Adaptive Linear Combined CFAR, ALC-CFAR, employs an adaptive composite approach based on the well-known cell averaging CFAR, CA-CFAR, and the ordered statistics, OS-CFAR, detectors. Data in the ref...

The detection performance of the generalized detector (GD) constructed based on the generalized approach to signal processing in noise is evaluated under homogeneous and non-homogeneous noise. The GD adaptive threshold is derived and defined applying an appropriate noise power estimation using the sliding window technique. The direct close expressions for the GD average probability of detection...

A new constant false alarm rate (CFAR) detection algorithm operating in non-homogeneous clutter is proposed in this paper. The proposed CFAR algorithm, CUT-inclusive (CI) CFAR, utilizes a goodness-of-fit test for determining and combining homogeneous windows, resulting in a higher detection performance. The CI-CFAR algorithm layout and analytical properties for the ideal case are investigated. ...

In this paper we describe software models of CA-CFAR, OS-CFAR and the TM-CFAR detectors in the receiver of the software defined radar. A comparative analysis of these CFAR detector models in terms of detection of radar targets in conditions of real clutter is performed. Software models of CFAR detector are implemented in MATLAB.

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 ...
