TL;DR: The initial analysis shows that such GSM passive radar system used as a transmitter of opportunity GSM BTS stations for vehicle traffic monitoring can be successfully used to extract traffic parameters such as the average speed of vehicles and road capacity.

TL;DR: The results presented in the paper show that a GSM-based PCL system can be used successfully in the future as a new system dedicated to speed control and traffic monitoring, both in urban areas and on small roads and highways.

TL;DR: In this article, a concept of passive bistatic SAR (PB-SAR) imaging using a spaceborne SAR radar transmitter of opportunity is presented, and the results of real passive SAR images are presented.

TL;DR: The paper presents the methods to overcome the problem end to exploit high RCS of the target in forward scattering region.

TL;DR: The concept presented is an alternative low-cost solution which can be successfully used in many applications where traditional active radars are nowadays commonly applied (e.g. speed control, traffic monitoring, etc.).
