Radio tomographic imaging and noise radar are two proven surveillance technologies. The novelty of fusing data from radio tomographic imaging and noise radar is achieved with the derivation of a fusion technique utilising Tikhonov regularisation. Ana

Large clutter discretes (LCDs) are spectrally bright localized clutter that can cause false alarms or missed target detections in space-time adaptive processing (STAP) data. For passive bistatic STAP, the LCD removal (LCDR) algorithm estimates the sp

As passive radar becomes more popular, modeling its behavior and physics becomes more critical. Particular to space-time adaptive processing (STAP) for ground moving target indication, the way in which clutter is modeled will directly impact performa

Communication waveforms act as signals of opportunity for passive radars. However, these signals of opportunity suffer from range-Doppler processing due to their high range sidelobes and pulse-diverse waveform aspects. Signals such as the long term e

Large clutter discretes (LCD) can cause either false alarms or missed target detections for ground moving target indication (GMTI). Typically, the effects of LCDs are mitigated by discarding the received data collected at the range bin of the LCD. Re

In passive radar, the receiver is limited to commercial waveforms from various emitters of opportunity. In addition, the geometry in three dimensional space between the receiver and various transmitters creates many performance considerations when ap

Ultra-wideband random noise radar theoretically has a thumbtack ambiguity function, which cannot be realized due to hardware, processing, and environmental limitations. Velocity estimation using traditional Doppler processing is not practicable for u
