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.
