Paper Abstract

A typical airborne ground surveillance radar is a multimode system with a ground moving target indicator (GMTI) mode for surveillance and tracking of moving ground targets and synthetic aperture radar (SAR) modes for imaging of terrain features and stationary ground targets. One of the key features of the GMTI mode is the ability to perform wide area surveillance (WAS) of a substantial ground area, and in addition to provide persistent surveillance of a pre-specified ground area over a long period of time. The accomplishment of this task requires careful optimization of radar parameters and careful planning of the platform orbits so as to minimize the time spent turning the aircraft and repositioning the radar. This paper defines the notion of surveillance orbit efficiency which, for constant speed flight, is simply the percentage of time spent on the straight legs of a race track orbit. It then examines the orbit efficiency for each of three cases depending on the assumed radar azimuth field of view (FOV). This paper is a modified version of work described in a MITRE Technical Report for the US Army.
