Target Reconstruction From Deceptively Jammed Single-Channel SAR

IEEE Transactions on Geoscience and Remote Sensing, 2018
This paper considers the problem of reconstructing true targets in a single-channel synthetic aperture radar (SAR) imaging system, which has been disturbed by deceptive jammings. Since the deceptive jammings are usually confined to the main lobe of an SAR antenna, their time–frequency distributions are different from those of the true echoes.

Target Reconstruction in Deceptively Jammed SAR via ADMM

IEEE Sensors Journal, 2019
This paper formulates an alternating direction method of multipliers (ADMM) approach to reconstruct true and false targets in a deceptively jammed synthetic aperture radar imagery based on characteristics extracted by dynamic synthetic apertures (DSAs).

An Admm Based Target Reconstruction Approach for Deceptively Jammed Sar

2018 IEEE 10th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2018
Deceptive jamming removal is a crucial problem for a synthetic aperture radar (SAR) to acquire information with high reliability. To tackle this problem, a dynamic synthetic aperture (DSA) approach has been proposed to reconstruct the true target based on a general SAR imaging mode.

The “Jam Roll” Flap for Fingertip Reconstruction

Plastic and Reconstructive Surgery, 1988
A method of fingertip reconstruction using a deepithelialized cross-finger flap in "jam roll" fashion is described. The technique has found relatively frequent indications.

Anti-jamming technique based on sampling reconstruction in parasitic spaceborne SAR system

IEEE International Radar Conference, 2005., 2005
For the problem of being unable to use spatial info directly to anti-jam in parasitic SAR system with sparse and irregular configured receivers, this paper proposes a new method to use spatial info. This method first uses multi-channel SAR on each small satellite, then uses the nonuniform data to reconstruct a uniform sequence, then uses space-time ...
