Passive bistatic radar or passive coherent location is gaining interest in the radar community, as it provides some advantages with respect to active radar. Passive radar does not aim to replace active radar; it provides a good complement to it. The computational effort that is required to implement the required signal processing is one of the drawbacks that affect passive radars. In this paper, a suboptimal but computationally affordable detection algorithm is investigated that is applicable to arbitrary waveforms (different types of illuminators of opportunity). First, a detailed mathematical formulation of the proposed suboptimum algorithm is derived. A theoretical performance analysis is then provided based on a comparison of the proposed with the optimum two-dimensional matched filter. Finally, simulated and real data are used to demonstrate the effectiveness of the proposed algorithm and to validate the theoretical performance analysis.

This paper presents work done on the application of Spatial Adaptive Processing (SAP) to Passive Bistatic Radar (PBR) systems. Specifically, the main goal is to analyse SAP performances in terms of interference spatial filtering and the estimation of the target's Direction of Arrival (DoA) when using PBR systems. Multiple solutions are provided and compared in order to identify the best multichannel processing architecture. Results are shown by using real multichannel PBR data

In this work, the capabilities of Passive Bistatic Radars (PBRs) for monitoring marine traffic and, more in general, for situation awareness in the proximity of a harbor have been addressed.Capabilities such as detection, tracking and possibily Inverse Synthetic Aperture Radar (ISAR) imaging have been demonstrated for maritime targets. The Livorno harbour has been considered as a specific case study as it is a relatively busy maritime hub. The experimental results have clearly shown that PBRs represent a viable solution for monitoring maritime traffic and to provide information for a common operational picture in harbour areas.
