Passive ISAR Imaging Using Multi-channel DVB-T Signals
This paper analysis the characteristics and ambiguity function of the single-channel and multichannel DVB-T signals, and choose the multi-channel DVB-T signal as opportunity illuminators to do the research of ISAR imaging. Firstly, the target’s echo using single-in-multi-out mode for passive ISAR image is derived, together with the analysis of the composition of the echo’s spatial spectrum. Con...
متن کاملNarrowband Passive Sonar Tracking
Passive sonar sensors are the main source of information for a submerged submarine. Modern sonar systems like ISUS 90 offer a number of acoustic antennas and combined signal processing for broadband and narrowband detection and analysis of target noise. While broadband detection is often used to obtain an overview of the targets surrounding the own ship, narrowband processing enables the detect...

متن کاملISAR for concealed objects imaging
A 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 trajectory as he moves in the vicinity of ...
متن کاملWide-angle Isar Passive Imaging Using Smoothed Pseudo Wigner-ville Distribution
We are investigating passive radar imaging of aircraft using reflected TV signals. UHF-band ISAR imaging requires wide-angle data to produce good cross-range resolution. We show that direct Fourier reconstruction (DFR) causes degradation of the reconstructed image due to aspect-dependent scattering. We find that a Smoothed Pseudo Wigner-Ville distribution (SPWVD) applied in the cross-range dire...
