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.

Multistatic-Radar Binomial Detection
IEEE Transactions on Aerospace and Electronic Systems, 1978The performance of multistatic-radar binomial detectors is investigated. Although conceptually similar to the well-knwn "M-out-of-N" detector frequently considered for monostatic systems, the multistatic detector must cope with false alarms generated by target et ghosting as well as by noise threshold crossings.

Human Detection With Radar: Dismount Detection
2012This chapter provides a brief overview of current systems and development efforts, kinematic and RCS models, technical challenges, and recently proposed novel ideas relating to human detection with radar. The expected radar return for a human target was analytically derived and the most widely used human kinematic model, the Boulic-Thalmann model, was ...

Radar detection performance calculations
2013An important application of the understanding of sea clutter developed in Chapters 2-4 is the prediction of radar detection performance. While many of the phenomena associated with sea clutter are not understood in detail in physical terms, empirically derived statistical models do provide us with the means with which we might calculate detection ...
