Abstract :
This paper presents a method to predict site-specific radar coverage. The method is based on solving the monostatic scattering problem by using the physical optics (PO) or Kirchhoff method, in combination with the use of geographical information systems, to model the specific terrain. The possibility to calculate the radar coverage, the time of arrival of the reflected pulses and the power delay profile allows the effect of clutter and multi-reflections to be analyzed in detail. Radar parameters, such as its location, antenna types, pulse duration and pulse repetition frequency can be optimized. Also, this information is of great interest in the design and improvement of sensitivity time control (STC) and constant false-alarm rate (CFAR) systems
