    The UNISYS Corporation has developed a microburst prediction radar (MBPR) to provide detection and short-term predictions of the most hazardous form of low altitude wind shear in the vicinity of an airport. The MBPR is intended for deployment on- or near-airport so as to minimize range coverage (and associated radar power-aperture) requirements. Like the airport surveillance radar wind shear proce...

    Researchers have developed and examined adaptive moving target indicator (MTI) techniques that are able to cope with significant clutter spectral spreading that occurs for a radar mounted on a moving platform. In particular, displaced phase centre antenna (DPCA) techniques and space-time adaptive processing (STAP) techniques have been applied to airborne and space-based radars (SBR). Much work has...

    The formation of low-frequency, ultra-wideband/widebeam (UWB/WB) SAR imagery faces inherent challenges not present in conventional SAR systems operating at higher frequencies. Small angle approximations and other shortcuts taken in conventional SAR processors may be inappropriate for the UWB/WB SAR processor. The severe range migration associated with fine resolution UWB/WB SAR poses a significant... View full abstract»

  • Adaptive chaff suppression by polarimetry with planar phased arrays at off-broadside

    Publication Year: 1995, Page(s):108 - 112
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (348 KB)

    Clutter with polarimetric signatures different from expected targets can be suppressed by reception orthogonal to the clutter echo polarization. It is shown that this capability is essentially reduced with targets outside the antenna normal direction. This is demonstrated by an example of chaff surrounding a strongly structured and fluctuating target observed with a uniformly transmitting and rece... View full abstract»

    A new multiresolution SAR image formation algorithm called planar subarray processing, PSAP, is presented. The PSAP provides the capability to perform intermediate decisions using lower resolution image data to redirect the remaining processing functions. These intermediate decisions can include, target detection, change detection, super resolution, and moving target parameter estimation. The PSAP... View full abstract»

    The paper considers the effectiveness of adaptive nullsteering in main lobe jamming scenarios. Four variants of algorithms are evaluated using data that has been gathered experimentally with an eight element array radar operating at C-band. The measurements were conducted in a coastal environment. Compared to fixed beamforming, an improved detection capability is clearly demonstrated. Furthermore,... View full abstract»

    The paper introduces a new coherent radar receiver structure that is optimum in the Neyman-Pearson sense in white noise. This new receiver structure is different from the pulse Doppler filter bank, and therefore refute the general understanding that the extension of the single Doppler filter to a Doppler filter bank is optimum when the target velocity is unknown. It examine the target detection pr... View full abstract»

    In a medium PRF radar, detection is ambiguous in both range and radial speed. The paper discusses some methods for the detection and resolution of range and radial speed in a radar with a burst oriented waveform, featuring PRF and RF changes from burst to burst. Two methods of detection are compared: (1) initial detection on a burst by burst basis and subsequent combination of the detections obtai... View full abstract»

    We show that the linear SIMD architecture FVIP is capable of performing a typical MPD radar signal processing including FFT and the resolving algorithm. A conventional DSP system clocked at 50 MHz would require approximately 200 DSPs to have the same performance as our FVIP system. We have estimated the size and power consumption of our FVIP system to be 3 dm3 and 200 W. With these MPD ... View full abstract»

    Initial steps towards the design of a fault detection module for radar and the setup of Kalman filtering for systematic error estimation in simulated and real radar data are described. The Kalman filter was set up in two different ways. The first setup assumed that a `perfect' reference trajectory was available, e.g., GPS data. Excellent results were obtained, when the Kalman filter estimated syst... View full abstract»

    Step frequency waveforms have been used in measurement radars in anechoic chambers for high resolution imaging of stationary or rotating targets in one or two dimensions. However in operational scenarios such as detection of moving targets, frequency step waveform spreads the target return and shifts the target range resulting in a loss of target magnitude, range accuracy and range resolution.
