Conventional receive digital beamforming (DBF) systems generally employ array architectures that use fixed radio frequency (RF) manifolds to combine the elements of several sub-apertures into a small number of digital channels. These channels are the

This paper presents a framework for incorporating knowledge sources directly in the space-time beamformer of airborne adaptive radars. The algorithm derivation follows the usual linearly-constrained minimum-variance (LCMV) space-time beamformer with

A new method is presented for describing the theoretical interference space-time covariance matrix that will be observed in an adaptive airborne radar system under specific topographical conditions. Both hot clutter that is induced by interfering sou

This chapter addresses the use of radar waveform optimization in radio frequency interference (RFI) scenarios that include either partial band interference or terrain-scattered interference (hot clutter). Terrain-scattered interference can induce sig

MIMO techniques induce a virtual extension of the antenna aperture, which results in lower MDV compared to conventional radar systems. Future work will include high-fidelity I/Q data simulations and experimental data collections to validate that the

This paper develops the theory of both optimum and adaptive MIMO radar. It is shown that the optimum MIMO transmit-receiver pair consists of a coupled multidimensional eigensystem and whitening matched filter. Also introduced, is an design procedure

Adaptive beamforming techniques such as space-time adaptive processing (STAP) combine spatial and temporal degrees of freedom to detect slow moving targets in strong clutter backgrounds. Many techniques exist for choosing the spatial and temporal deg

This paper presents practical radar waveform design algorithms for colored noise mitigation. One algorithm uses an iterative least squares approach to form a hybrid waveform that simultaneously maximizes SINR and minimizes peak side-lobe levels under

Radar systems have long been plagued by poor cross range (azimuthal) resolution due to the standoff range of the sensors and limitations of aperture size and beamwidth. This problem is especially an issue for sensors operating in the VHF and UHF band
