Abstract :
This paper describes a 24 GHz radar receiver array, designed to detect and image termite activity, behind a wall, floor or ceiling. This hybrid array is composed of two sub-arrays. A Direction of Arrival (DOA) sub-array for wide area detection of termites, and a 3D high resolution imaging sub-array for imaging individual termites. Here, we introduce an enhanced DOA algorithm, to resolve arbitrary numbers of targets, and compare simulation results with video of actual termites.
