Abstract: A system for geolocating a radio frequency (RF) transmitter in the presence of multipath interference may include a plurality of RF receivers arranged in spaced relation. The system may also include a controller coupled to the plurality of receivers and configured to generate a plurality of measurements associated with the RF transmitter. The controller may also compute a plurality of ambiguity functions based upon the plurality of measurements and due to the multipath interference, and project the plurality of ambiguity functions onto a common geo-referenced grid. The controller may also detect a peak on the common geo-referenced grid indicative of a geolocation of the RF transmitter.

Abstract: A radar system may include an antenna, a waveform generator for generating a plurality of waveforms for different polarizations and/or having different frequency components, and a transmitter connected to the waveform generator for transmitting the plurality of waveforms via the antenna. Moreover, the radar system may also include a receiver connected to the antenna for receiving reflected signals from targets, and a processor for iteratively deconvolving the reflected signals to generate target data. More particularly, the radar system and targets may be relatively movable with respect to one another, and the processor may therefore store reflected signals over a length of relative movement and generate the target data based upon the stored signals to thus provide a synthetic aperture radar (SAR) system or an inverse SAR (ISAR) system.
