This paper addresses target detection in passive multiple-input multiple-output (MIMO) radar networks comprised of non-cooperative transmitters and multichannel receivers. A generalized likelihood ratio test is derived, and approximate test statistic distributions are presented for both hypotheses under common scenario conditions. Analysis and simulation(More)
This work addresses the problem of target detection in passive multiple-input multiple-output (MIMO) radar networks without utilization of direct-path reference signals. A generalized likelihood ratio test for this problem is derived, and the distribution of the test statistic is identified under both hypotheses. Equivalence is established between passive(More)
Conventional passive multistatic radar systems, which are comprised of multiple transmitters and receivers, detect and localize targets in a two-stage process. First, detections are performed independently for each bistatic transmit-receive pair. A multilateration process then uses the resulting bistatic range estimates to localize the targets in Cartesian(More)
A new modeling method for representing distributed scattering centers in wide-angle synthetic aperture radar (SAR) is presented. The proposed multipeak model approximates amplitudes of localized image peaks that typically appear at a single pixel or as an in-line set of pixels in a SAR image. In this way, the multipeak model is an improvement over existing(More)
Attributed scattering center models can relate radar measurements to physical target features. This paper summarizes recent signal processing methods for attributing synthetic aperture radar images with emphasis on feature space definition for object recognition. Examples using laboratory measured inverse synthetic aperture radar data and simulated data are(More)
Modern remote sensing applications, including radar, require thoughtful consideration of electromagnetic principles for constructing advanced signal processing algorithms for detection, estimation, tracking, imaging and feature extraction. Starting from a generalized picture of the distributed sensing paradigm, this paper presents current efforts at the(More)
A spatial filtering method is introduced for improving continuous-wave inverse synthetic aperture radar (ISAR) measurements in a partially controlled chamber. Twodimensional angle of arrival (AoA) estimation using a modified matrix pencil algorithm first identifies directions of interference sources outside the target zone. Then, each radar sweep is(More)
In recent years, a novel mathematical framework for analyzing and designing multistatic radar systems has been proposed. It was argued through numerous simulation examples that multistatic radar system performances can be significantly improved by shaping the multistatic ambiguity function. Based on this framework, rules for waveform selection, sensor(More)
