Airborne interceptor radars at uhf or l-band with conformal wingmounted array antennas and digital signal processing are of interest for future systems. adaptive control of the angle/doppler response of these radars, using array element outputs, multiple beam outputs, or sub-aperture outputs… More

A new class of array called the spatially diverse coherent array (sdca) is proposed for study. such arrays use a new concept introduced here--the simultaneous transmission of independent waveform from different configurations of elements comprising the array. when combined coherently on receive via… More

Space based radars with lens or reflector antennas can readily provide multiple beam outputs. other sbr designed to detect and track aircraft, including systems with corporate fed array antennas, may provide monopulse sum and difference outputs for angle measurement. a method is described for… More

Airborne radars for the detection and targeting of low cross section ground vehicles must transmit more power, use larger antennas, and/or operate at shorter ranges to achieve the required signal-to-noise ratios. in addition, a major improvement in subclutter visibility is required. this proposal… More

An adaptive array signal processor capable of adaptively nulling multipe sidelobe jammers and sidelobe distributed and discrete ground clutter returnes competing with the target return, in ai-low observable target detecting medium-prf radars is the subject of a design study. the asi-developed… More

Long wavelength ground-based multistatic radar systems which may be in the hf, vhf, or uhf bands offer potential solutions to the problems associated with performing the tactical army mission of foreward area air defense (faad) and weapons location with monostatic short wavelength radars. however,… More

Monostatic radar systems using space-time adaptive procesing (stap) have been simulated in detail and shown to provide large improvements in moving target detection. and tracking capability. the proposed study will apply stap technology to bistatic radars with airborne receivers and airborne or… More

Adaptive digital array processing in airborne radars can provide a major improvement in target detectability by adaptively suppressing clutter and jamming. the effectiveness of this spacetime adaptive processing has been demonstrated by detailed simulation at asi. recently, array radar flight test… More

A target angle estimation technique making effective use of the spatial degrees of freedom of an adaptive array radar system has been developed by ASI and demonstrated to yield unbiased and efficient angle estimates in near-main beam jammer environments. The program objective of progressing towards… More

Potential cost effective proprietary solutions to a number of outstanding problems involved in achieving an SBR capable of meeting military surveillance and reconnaissance requirement for the detection and track of both ground and airborne moving targets are proposed to be further developed and … More

Not Available Recently NZ Applied Technologies (NZAT) has successfully coated on standard single-mode optical fibers with resistive, piezoelectric, magnetostrictive materials such as Ti/Pt, ZnO, PZT, PLZT, FeCo and Terfenol-D. This technology opens a new area for fiber-optic sensor applications by… More
