High-performance radar calls for sliding MTD (SMTD). Traditional SMTD processing massively increases computational load, resulting in difficulty of implementation. A modified moving DFT algorithm and a new SMTD structure are proposed in this paper. The new SMTD structure adopts both batch-mode signal channel estimation and the modified moving DFT algorithm, which leads to a dramatic reduction of the computational load. The new SMTD structure can be regarded as an adaptive filter for other applications as well.","PeriodicalId":286281,"journal":{"name":"Record of the IEEE 2000 International Radar Conference [Cat.

The restriction of the sensor output to one bit certainly implies a substantial information loss. We, therefore, investigate optimal decision rules in a multi-bit detection network. A multi-bit decision is equivalent to multiple level quantization of the likelihood ratio. In this paper, we develop an iterative algorithm to determine the quantization levels in each of the independent local sensors. Our method is efficient and its asymptotic convergence is guaranteed. We demonstrate the feasibility of the proposed approach through the application to a radar detection problem that is CFAR detection of Rayleigh fluctuating targets in Gaussian noise. Simulation results are presented to show how the additional bits from local sensors could result in a better detection performance.","PeriodicalId":286281,"journal":{"name":"Record of the IEEE 2000 International Radar Conference [Cat.

The chaotic predictors are user to estimate the clutter (i.e., modulation component), while the statistical detectors are used at the output of the squared residual error of the chaotic predictor. Here, the background clutter is this error component and any man-made point target that may be present. The residual error consists of the residual modulation component, the speckle and additive thermal noise. The proposed detector has been used for detecting man-made point targets using a wide range of radar data. Detection of small man-made targets in radar or infrared clutter is an important area of interest for many applications such as ocean surveillance, search and rescue, remote sensing, mine detection, etc. It has been shown that infrared and radar clutter exhibit chaotic rather than purely random behaviour. From the chaotic point of view, a neural network predictor has been developed using a generalized regression neural network (GRNN).","PeriodicalId":286281,"journal":{"name":"Record of the IEEE 2000 International Radar Conference [Cat.

When the signal to be detected is embedded in correlated Gaussian distributed clutter, the optimum Neyman-Pearson detector is the linear whitening matched filter (MF). The contribution of the present paper is to investigate, by means of L-band measured ground clutter data, the robustness of the linear matched filter operating in a Gaussian environment in the presence of a mismatch between the design clutter power spectral density (PSD) shape and the actual shape. The well-known Gaussian and power-law PSD are compared to the exponential PSD that has been revealed by experimental measurements carried out by the MIT Lincoln Laboratory (MIT-LL) Phase One and LCE (L-Band Clutter Experiment) coherent radars on ground clutter data. The parameters of these three models are estimated by means of a nonlinear least squares (NLLS) method. The impact of the spectral models on the performance of the matched filter is investigated in terms of improvement factor (IF), probability of false alarm and probability of detection. The numerical results of this paper validate the exponential clutter spectral model for windblown foliage by showing that the differences between using actual measured in-phase and quadrature clutter data and modeled clutter spectral data of various spectral shapes are minimized when the spectral model employed is of exponential shape. Our conclusions are summarized.","PeriodicalId":286281,"journal":{"name":"Record of the IEEE 2000 International Radar Conference [Cat.

The difference in models of received echoes backscattered from the extended scene and point like moving target between the SAR and airborne early warning (AEW) system is investigated and it shows that the quadric phase can not be ignored in the SAR system as in the AEW system due to its long coherent processing period. A modified STAP is put forward to suppress the clutter whilst retaining the phase history of the moving target. The concept of the \"weight signal\" is proposed to retrieve the phase history of the moving target, which is damaged by the STAP due to the optimum SAR clutter cancellation.
