Determination of the Possible Locations of the Receiver on a Passive Coherent Location System, Considering the Effects of the Terrain and the Atmospheric Conditions

摘要

It has always been an issue for an armed force, or government, to obtain complete radar coverage over an area of interest. Generally, this objective remains unaccomplished due to geographical, technical, and/or operational reasons (meaning topographic obstacles, transmitted power, extreme isolation, hierarchy of objectives, etc.) The fact of having vast areas of territory beyond radar coverage can be decisive in an armed conflict. With the recent resurgence of bistatic radar theory and applications, now in the form of Passive Coherent Location (PCL) systems, using existing signal sources (TC and Radio Stations) it is possible to decrease the blind zones of a country's air defense system, in a somehow economic and effective way. The general purpose of this thesis is to develop a methodology to determine possible receiver locations needed to implement a PCL system, while emphasizing low altitude coverage, specific terrain and atmospheric information, available signal sources and the needed for coverage.
