چکیده

Techniques for detection performance prediction for maritime surveillance radars are described, with particular emphasis on the use of the compound K-distribution model for radar sea clutter. The paper first briefly reviews the analytical methods for deriving theoretical detection performance limits using compound models for both clutter and targets. Next, it is shown how the clutter environment is modelled for radar design evaluation, and methods whereby the radar may adapt to this changing environment for optimum target detection performance are described. This is followed by a description of a new method for performance prediction for a cell-averaging CFAR in real clutter, using recorded clutter signals but avoiding lengthy computer simulations. Finally, possible future developments of maritime surveillance radars are discussed.

Nonlinear processing of high resolution radar sea clutter

Surveillance radars used at sea need to suppress the signal received back from the sea surface, in order to improve the probability of detecting target signals. This paper investigates whether nonlinear predictor networks can be used to improve the suppression of sea clutter, and thus to improve the performance of maritime surveillance radar detectors.

Effect of Curved Path Monopulse Radar Platform’s Grazing Angle on Height of Floated Targets Detection

Monopulse radarsare one of the most accurate tracking radars used to guide various platforms. Detection and tracking of surface targets with these radars are performed in order to point strike targets. Sea clutter presents challenges for detecting floated targets and in addition to affecting detection height, it can cause errors in monopulse angle finding. In this paper, the airborne monopulse ...

Coherent Multilook Radar Detection for Targets in KK-Distributed Clutter

This Chapter examines the problem of coherent multilook radar detection of targets in the sea from an airborne maritime surveillance platform. The radar of interest operates at high resolution, and at a high grazing angle, with frequency in X-Band, and is fully polarised. Typically, such surveillance radars are searching for small targets, such as fishing boats or submarine periscopes. When a r...

Radar Signal Detection in K-distributed Clutter by Pade Approximation

In this paper, two suboptimum detectors are proposed for coherent radar signal detection in K-distributed clutter. Assuming certain values for several initial moments of clutter amplitude, the characteristic function of the clutter amplitude is approximated by a limited series. Using the Pade approximation, it is then converted to a rational fraction. Thus, the pdf of the clutter amplitude is o...
