Coherent multistatic ISAR imaging
IET International Conference on Radar Systems (Radar 2012), 2012This paper presents methods for Coherent Multistatic Radar Imaging for Non Cooperative Target Recognition (NCTR) with a network of radar sensors. Coherent Multistatic Radar Imaging is based on an extension of existing monostatic ISAR algorithms to the multistatic environment.

Multistatic, multifrequency scattering from zooplankton
The Journal of the Acoustical Society of America, 1998Very satisfactory results have been obtained in estimating size abundances of small zooplankton such as copepods from inversion of multifrequency backscattering measurements. Application of this method has become almost routine in many situations. Fluctuations in the scatterer physical properties (density and compressibility) tend principally to cause ...

This chapter discusses the key elements in the design of a distributed multistatic synthetic aperture radar mission. A number of application domains are discussed, with an emphasis on single- and multi-baseline interferometric techniques, deriving lower and upper bounds to the required spacecraft separation.

Narrowband multistatic ISAR imagery system
Proceedings. 2005 IEEE International Geoscience and Remote Sensing Symposium, 2005. IGARSS '05., 2005This article deals with the imagery of mobile targets by using a multistatic radar (several transmitters and one receiver). First, we develop an original multistatic algorithm based on spatio-temporal SAR methods. As the transmitted signal is narrowband and the central frequency is weak, the final resolutions of the image depend on two parameters: the ...

Multistatic Sonar Localization
IEEE Journal of Oceanic Engineering, 2006This paper develops bistatic contact-localization statistics as a function of source-target-receiver geometry, source and receiver location errors, sound-speed errors, time and bearing errors, and array-heading errors. We verify the analysis through Monte Carlo simulation and illustrate localization accuracy for some representative choices of source ...

Optimizing multistatic sonobuoy placement
The Journal of the Acoustical Society of America, 2005Sonobuoy patterns for monostatic sensors were developed during the Cold War for deep, uniform underwater environments, where a simple median detection range defined a fixed inter-buoy spacing (usually along staggered lines). Oceanographic and acoustic conditions in littoral environments are so complex and dynamic that spatial and temporal variability ...

Range only multistatic tracking
2010 13th International Conference on Information Fusion, 2010Multistatic tracking involves using non-collocated transmitters and receivers to track the targets. In this paper we also assume no angle information. This paper proposes an approach using Gaussian Mixture representation of measurement uncertainty. An arbitrary number of receivers can be used using this approach.

Multistatic radar micro-Doppler
2020This chapter reviews how multistatic radar sensor networks can be utilised to sense a series of different moving targets to extract their micro-Doppler (μD) signatures and use these for classification purposes. The field of radar has advanced significantly since its inception in the early twentieth century.

In this chapter, the attention is turned toward multistatic passive radar systems on airborne platforms for the purpose of synthetic aperture radar (SAR) image creation. A passive radar system is a special type of bistatic radar that exploits noncooperative transmitters as its source of illumination.
