Sensitive target detection and accurate direction-of-arrival (DOA) estimation are key goals of the modern phased array radar designer. To this end, a high number of receiving antenna elements is necessary. This inevitably leads to a high computationa

In this paper we regard an approach to fast sparsity-based GMTI processing for an air-or space-borne along track antenna array. The idea for this algorithm was inspired by a technique called fast compressive sensing based on approximated observation

One efficient method to detect slow targets with low signal-to-clutter-plus-noise ratios is space time adaptive processing (STAP). To apply STAP to maritime radar systems, the multichannel properties of sea clutter have to be known. This paper invest

Ground penetrating radar (GPR) target detection and classification is a challenging task. Here, we consider online dictionary learning (DL) methods to obtain sparse representations (SR) of the GPR data to enhance feature extraction for target classif

In this article we present the realization of an experimental multistatic inverse synthetic aperture radar (M-ISAR) system. The primary focus of this work is to utilize the multistatic geometry to estimate the motion of a maneuvering ground target. W

This paper presents a new bistatic point target reference spectrum. It is derived by using the 2-D principle of stationary phase which is first applied in the synthetic aperture radar (SAR) community. The spectrum contains two hyperbolic range-azimut
