TL;DR: This paper compares two algorithms for three-dimensional target localization from passive radar measurements, namely spherical interpolation (SI) and spherical intersection (SX), based on closed-form equations.

TL;DR: In this paper, a study of passive coherent location (PCL) radar performance for the case when a distant, weak target echo is shadowed by strong echoes is presented, which increases PCL radar performance in the distant zone by adaptive removal of strong echoes from the received signal.

TL;DR: The presented technique allows flight parameters to be estimated with accuracy that is independent of the initial velocity error, and can be used for real-time processing for both Earth imaging and moving-target indication.

TL;DR: A new class of signal processing algorithm based on CLEAN methods primary introduced in radio-astronomy is presented in the paper and several techniques for radar signal processing utilizing CLEAN concept are shown.

TL;DR: A family of passive coherent location (PCL) radar demonstrators, called PaRaDe (passive radar demonstrator), which were developed at Warsaw University of Technology are presented.
