On-board PCL systems for airborne platform protection

The paper presents the idea of application of passive radar (PCL) on board of an airplane. The aim of the PCL system is to provide surveillance information to the pilot (or autopilot), to detect the targets in the surveillance space and to protect the platform from collisions and other threats. The PCL system can use the available emitters of opportunity, mainly DBV-T transmitters. Other sources of illuminations, such as analogue (FM) or digital radio (DAB) can be used as well.
