This article presents a novel approach to the estimation of motion parameters of objects in passive forward scattering radars (PFSR). In such systems, most frequency modulated signals which are used have parameters that depend on the geometry of a ra

Today the main applications of ground based passive coherent location (PCL) systems are in the domain of air traffic surveillance–air target detection, tracking, and localization. Interest in using PCL radars in these applications is expressed prim

In the paper the influence of presence of noise in the reference signal on signal processing algorithms of a passive radar is analyzed through a comparison with results for noiseless reference signal. As a result upper limits of improvements resultin

In this article, a concept of passive bistatic SAR (PB-SAR) imaging using a spaceborne SAR radar transmitter of opportunity is presented. This was proposed for the first time in the beginning of this century by Krieger et al and Griffiths et al. Beca

Most of PCL algorithms require clear, non channel-distorted reference signals. However radar systems operate under various environmental circumstances, including dense, multi-path urbanized areas. GSM transmission has built-in mechanism to estimate a

The classical passive radar has very low sensitivity in the direction of the transmitter. The sensitivity losses in this direction are caused by the direct signal removal procedure. The application of digital reconstruction algorithms can significant
