Continuing advances in radar technology are driven both by new application regimes and technological innovations. A family of applications of increasing importance is detection of a mobile target intruding into a protected area, and one type of radar system architecture potentially well suited to this type of application entails a network of cooperating radars. In this paper, we study optimal r...

The detection of slow moving targets by a moving bistatic pulsed Doppler radar system is addressed. Optimum clutter rejection is achieved using space-time adaptive processing (STAP). This requires estimating the clutter-plus-noise covariance matrix using a sequence of snapshots at successive ranges. For most monostatic and for all bistatic radar configurations, these snapshots are rangedependan...

Introduction: Bistatic radar measurements of the lunar surface are being carried out by the Mini-RF team using Arecibo as a transmitter, cf. Fig. 1. The resulting radar images – the first to be collected at non-zero bistatic phase angle β (between source and receiver) – are being studied extensively to test the hypothesis that water ice resides inside permanently shadowed and perhaps other very...

Bistatic frequency-modulated continuous wave (FMCW) synthetic aperture radar (SAR) mounts the radar transmitter and receiver on separate platforms, which offers considerable capabilities, reliability and flexibility in designing FMCW SAR missions. Moreover, the spatial separation achieves better isolation between transmission and reception channels compared with the monostatic FMCW SAR where th...

This research presents an ambiguity function analysis of the digital audio broadcast (DAB) waveform and one signal detection approach based on signal space projection techniques that effectively filters the direct-path signal from the receiver target channel. Currently, most Passive Coherent Location (PCL) research efforts are focused and based on frequency modulated (FM) radio broadcasts and a...

Bistatic synthetic aperture radar (SAR) imaging from very asymmetric configuration is a promising technique for both military and civilian issues. Indeed, an illuminating radar standing off at a safe distance may be combined with a low cost, possibly unmanned air vehicle using a passive radar receiver operating at closer range. Practical civilian application could be high resolution remote sens...

This tutorial provides a discussion of the application of knowledge-based processing techniques to emerging technologies. Following the third of the tutorials in this series we interpret knowledge-based processing as the use of adaptivity and the exploitation of prior knowledge in such a way as to choose the optimum processing method in each case. We interpret ‘emerging technologies’ as novel a...

During the Clementine 1 mission, a bistatic radar experiment measured the magnitude and polarization of the radar echo versus bistatic angle, beta, for selected lunar areas. Observations of the lunar south pole yield a same-sense polarization enhancement around beta = 0. Analysis shows that the observed enhancement is localized to the permanently shadowed regions of the lunar south pole. Radar ...
