In this paper, we estimate the sensitivity of the adaptive censoring algorithm towards the change of the input parameters of pulse jamming of an Adaptive Postdetection Integration (API) CFAR processor. The censoring algorithm estimates the background environment and automatically defines the scale factor. We propose this algorithm to be used for the estimation of both, the probability of appear...

A constant false alarm rate (CFAR) algorithm has been developed for use in multi-band mine detection. While it is often difficult to predict the spectral signatures of targets, the shape of the target may be known. This test exploits geometric target features and spectral differences between the target and the surrounding area. The algorithm is derived from a general statistical model of the da...

We have developed linear subspace detectors that detect targets in a background of both noise and tree responses. We consider the background clutter as stochastic noise, and we model the tree responses as a deterministic signal with unknown amplitude and unknown parameters. We develop a family of target detectors based on different assumptions on what is known about the taget and the tree famil...

Change detection, the comparison of remote sensing images from different moments in time, is an important technique in environmental earth observation and security. SAR change detection is useful when weather and light conditions are unfavourable. Five methods of SAR change detection are presented and evaluated. The performance of the first one, post-classification change detection, is strongly...

Imaging technology enhances radar environment awareness. can provide richer target information for traffic management systems than conventional detection radar. However, there is still a lack of research on millimeter-wave imaging urban surveillance. To solve the above problem, we propose an improved three-dimensional FFT algorithm architecture roadside in scenarios, enabling concurrence dynami...
