This chapter focuses on ISAR signal processing techniques. As already stated in Chapter 1, ISAR is another way to face the problem of forming high resolution radar images of targets. Differently from SAR, ISAR techniques exploit the target motion to form e.m. images of the illuminated targets.

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.

Hybrid SAR/ISAR for distributed ISAR imaging of moving targets
2015 IEEE Radar Conference (RadarCon), 2015The hybrid SAR/ISAR processing takes advantages of both SAR and ISAR to generate high-resolution imagery of moving targets. In this paper, we introduce the concept of hybrid SAR/ISAR, discuss how to reform a high-resolution imagery of moving targets and extract 3-D target feature through hybrid processing of the data taken by multiple arbitrarily ...

Simulations of ISAR image errors
IEEE Transactions on Instrumentation and Measurement, 1990The authors present concepts and show simulation results for a number of situations where the ISAR (inverse synthetic aperture radar) image is degraded by errors introduced by the signal acquisition and data processing. These errors result in degradation of resolution, false targets in the image, geometric distortion of the image, incorrect values for ...

ISAR for concealed objects imaging
SPIE Proceedings, 2015A new promising architecture of microwave personnel screening system is analyzed in this paper with numerical simulations. This architecture is based on the concept of inverse aperture synthesis applied to a naturally moving person. The extent of the synthetic aperture is formed by a stationary vertical linear antenna array and by a length of subject’s
