  • A novel approach for pattern synthesis of arbitrary array

    Publication Year: 1996, Page(s):457 - 460
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (316 KB)

    In this paper, a novel approach, based on the genetic algorithm, for pattern synthesis of an arbitrary array is presented. Unlike conventional genetic algorithms dealing with binary coding and genetic operations, this algorithm avoids coding and uses decimal operation, directly dealing with real or complex coefficients. Furthermore, constraints on the phases of the complex coefficients can be impo... View full abstract»

  • Adaptive clutter suppression for low PRF heliborne reconnaissance radar

    Publication Year: 1996, Page(s):389 - 392
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (304 KB)

    Adaptive spatial-temporal processing techniques have been widely applied to suppressing clutter and interference in airborne radar. However, it is pointed out that the clutter received by low PRF heliborne radar has many traits different from that received by AEW radar. A new approach called the adaptive beamformer-DPCA cascade processing is proposed, and the detection performance is compared with... View full abstract»

    Currently, the accuracy of SSR-data is better than ADS-data, but ADS-data can provide surveillance in some areas which is not covered by radar. So through integrating these two types of data we can overcome some shortcomings of the data and gain the best results. This paper compares the two types of surveillance data, discusses the contributions of ADS-SSR data and the key technology of integratin... View full abstract»

  • An approach to improve the image quality in Doppler beam sharpening

    Publication Year: 1996, Page(s):452 - 456
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (332 KB)

    In Doppler beam sharpening (DBS), an effective approach to eliminate correlated speckle is uncorrelated accumulation of several images in the azimuth dimension. However, if the centroid of the images to accumulate has a registration error, the uncorrelated accumulation will have azimuth ambiguity. In order to reduce the azimuth ambiguity, an approach to smoothing the Doppler centroids estimated fr... View full abstract»

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (524 KB)

    Space-time adaptive processing (STAP) has shown to be an efficient tool for detection of slow targets (moving target imaging, MTI) in a strong clutter environment by air- or spaceborne radar. STAP algorithms have the attractive property of implicitly compensating for the clutter Doppler spread induced by the radar platform motion. STAP techniques have been discussed for application with sidelookin... View full abstract»

    Space-time adaptive processing (STAP) is a joint angle-Doppler domain filtering technique developed for minimizing the effects of various kinds of interference on target detection. That is, the angle-Doppler response pattern of a STAP based system can be adapted to the very complicated varying interference environment of airborne radar. This paper provides an overview of major issues in STAP devel... View full abstract»

  • Fourier reconstruction in spotlight mode SAR imaging

    Publication Year: 1996, Page(s):338 - 341
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (332 KB)

    The spotlight mode SAR imaging procedure can be modeled in two ways. One is from the projectional information introduced from computer-aided tomography (CAT) founded on the projection-slice theorem. By quoting the concept “projection” from CAT to microwave imaging, the spotlight mode SAR can be interpreted as a narrow band tomography reconstruction problem in the far field and small ro...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (196 KB)

    The coherent imaging principle of synthetic aperture radar results in speckle noise in the SAR images, seriously reducing the image quality. This paper divides the SAR image into small regions of similar distribution characteristics, and reduce the speckle noise in the different regions. This algorithm has very good speckle reduction rate, while protecting the edge-characteristics of the image. Ex... View full abstract»

    This paper presents a non-adaptive spatial-temporal 2-D signal processing for suppressing ground clutter received from side-looking phased array of airborne early warning radar. Since the clutter signal has the same complex envelope value located in a skew line of 2-D plane, the skew-canceling processing can completely cancel the clutter with the value of the corresponding canceling point on this ...

    Under the condition of jamming the number of usable measurements in a T/R-R bistatic system is variable. Therefore it is necessary to study some location and tracking algorithms concerning different sets of measurement data. The multi-stage tracking technique proposed makes full use of measurement data in T/R and R stations under different condition of jamming, as a result the tracking precision o... View full abstract»

    This paper proposes a new method for estimating a target's manoeuvre value. The method consists of a Bayesian scheme for identifying the possible range of a target's manoeuvre magnitude and a multiple-hypothesis scheme for estimating its value. The parameters of the multiple-hypothesis scheme are dynamically adjusted with the variation of a target's manoeuvring behavior. The dynamic adjustment hel... View full abstract»
