Compressive CFAR radar detection
2012 IEEE Radar Conference, 2012In this paper we develop the first Compressive Sensing (CS) adaptive radar detector. We propose three novel architectures and demonstrate how a classical Constant False Alarm Rate (CFAR) detector can be combined with l 1 -norm minimization. Using asymptotic arguments and the Complex Approximate Message Passing (CAMP) algorithm we characterize the ...

Target detection is a probabilistic idea; noise and clutter prevent us from being certain to find the targets we are looking for, and will normally present us with plenty of 'targets' we are not looking for. We can only define the probabilities of detection and of false alarm that we are prepared to live with.

Radar waveform synthesis method--A new radar detection scheme
IEEE Transactions on Antennas and Propagation, 1980A new scheme for radar detection and discrimination, the radar waveform synthesis method, is investigated. This scheme consists of synthesizing the waveform of an incident radar signal which excites the target in such a way that the return radar signal from the target contains only a single natural resonance mode of the target.

The performance of marine radar for ice detection is investigated using iceberg observational data collected during three years of offshore drilling in the Labrador Sea region. One thousand "first sightings" of icebergs during drilling operations revealed a maximum range of detection of 87km, with the median value being 27.8km.

Radar detection is a particular kind of binary decision problem. Initially we shall make the simplifying assumption that the signal space also consists of only two elements and require the receiver to determine in the presence of channel disturbances whether s 1 or s 0 has been transmitted (to choose a 1 or a 0, respectively), where s 1 corresponds to ...

Target detection is one of the very first operations, which has to be performed on received radar signal. The purpose of detection is normally to distinguish genuine target reflections from noise and clutter. This chapter discusses the main concepts and methods used for radar detection.

Clutter is defined as any unwanted radar return. The presence of clutter in a range/Doppler cell complicates the detection of a target return signal in that cell. In order to quantify the effect of clutter on the probability of detection, we must first specify sets of models suitable for representing the clutter and target. The simplest and most common

Abstract Damaging hailstorms are rare but are significant meteorological phenomena from the point of view of economic losses in central Europe. Because of the high spatial and temporal variability of hail, the proper detection of hail occurrences is almost impossible using ground station reports alone.

The potential applicability of multiple-channel coherence estimation in situations where one channel contains a noise-free signal replica (as in active radar) or a high-SNR reference signal (as in passive coherent radar) has been proposed in recent work.
