Passive Bistatic Radar (PBR) has significant civilian and military applications due to its ability detect low-altitude targets. However, the uncontrollable characteristics of transmitter often lead subpar target detection performance, primarily a low signal-to-noise ratio (SNR). Coherent accumulation typically limited improve SNR in presence strong noise clutter. In this paper, we propose an ad...

Bistatic radar is an active microwave sensor operating with separated transmitting and receiving antennae. This paper deals with a spaceborne mission of a bistatic synthetic aperture radar based on a small satellite flying in formation with ENVISAT along parallel orbits, and equipped with a receiving only microwave system, which catches the ASAR echoes. The proposed system does not require any ...

In this paper, an effective target detection and localization method is proposed for a passive bistatic radar (PBR) system. The PBR system consists of a commercial FM radio station, which is a noncooperative illuminator of opportunity (IO), referred to as the transmitter antenna and multiple surveillance antennas that form an antenna array, e.g., uniform linear array (ULA). Unlike other literat...

A set of theoretical techniques to prevent a radar from being used by a bistatic radar receiver as a non-cooperative illuminator are analysed. This works by radiating in addition to the radar signal waveform, a ‘masking signal’ waveform which is orthogonal to the radar signal waveform, both in the coding domain and the spatial domain. A number of different coding schemes are analysed. Two spati...

Ronald Mahler’s Probability Hypothesis Density (PHD) provides a promising framework for the passive coherent location of targets observed via multiple bistatic radar measurements. We consider tracking targets using only range measurements from a simple non-directional receiver that exploits non-cooperative FM radio transmitters as its “illuminators of opportunity.” A target cannot be located at...
