In the paper, an analysis of bistatic tracking accuracy in passive radar is presented. The influence of parameters such as integration time, probability of false alarm, signal-to-noise ratio and spectral density of process noise is investigated. Simulations are performed for three popular types of illuminators of opportunity: FM, DAB and DVB-T.
This paper presents a robust detection scheme for continuous wave noise radar in the presence of heavy-tailed interferences described by alpha-stable probability distributions. The conventional detection algorithm based on second order statistics may reveal significant performance degradation in the presence of impulsive noises. A substantial advantage of presented robust algorithm based on lower...
The paper presents the effect caused by the presence of target echoes in the reference channel of bi- or multistatic noise or pseudo-noise radar. Most of the paper on multistatic radars assume that the reference signal is ideal one. In the case, when reference signal is received by directional reference antenna, it can be contaminated by echo signals originated from stationary target like ground clutter...
A continuous wave noise radar receives all the echoes simultaneously. Thus, strong echoes of nearby targets mask the weak echoes of far targets. Even if the echoes are separated in Doppler and in range, the strong echo produces relatively high sidelobes at the output of the correlation receiver. The sidelobes may prevent the detection of a weaker echo. Classical methods of strong echo removal, based...
