Passive Radar signifying the localisation of a target by radar measurements without using own controlled emissions has been discussed, tried, reinvented, and matured within the last 80 years. Its advantages, like covert operation and saving the costs

Detecting targets embedded in noise and clutter is an essential task for many radar systems. A competent system must additionally offer high probability of detection with a low false alarm rate and a standard practice is to employ constant false alar

This letter aims to show the potential of using polarimetric parameters to distinguish between large birds and unmanned aerial vehicles (UAVs) of comparable size in the context of a modern long-range air defense radar. Time is a critical resource in

This paper presents an application of compressed sensing in a pulsed system, such as a radar or sonar to form range-Doppler maps. Instead of transmitting a train of pulses, we portrait a system where the pulse emission itself takes place in a sparse

Radar target detection is a fundamental process in order to differentiate objects of interest and separate them from background noise. A desired objective in detection operations is to satisfy two very contradictory requirements: offer a high probabi

Adaptive beamforming (ABF) for maximizing the signal to interference plus noise ratio (SINR) is applied to acquisitions made by a passive bistatic radar (PBR) exposed to strong direct signal interference (DSI). The DVB-T transmitter was located appro

The use of frequency agility has a proven track record in radar systems. Altering the radar carrier frequency over shorter intervals improves the detection capabilities for slowly fluctuating targets and increases jamming resistance. This article exp

A fully adaptive radar framework has been proposed in recent publications, and this paper will implement the framework in an adaptive update rate application for a tracking radar. A cost function is developed to balance the radar resource usage with
