Airborne Forward-Looking Radar Super-Resolution Imaging Using Iterative Adaptive Approach
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2019Airborne forward-looking radar (AFLR) imaging has raised many concerns in fields of Earth observation, independent of weather and daytime. Constrained by imaging principles, conventional high-resolution radar imaging techniques such as synthetic aperture

Earth-based radar has been one of the few, and one of the most important, sources of new information about Mercury during the three decades since the Mariner 10 encounters. The emphasis during the past 15 years has been on full-disk, dual-polarization imaging of the planet, an effort that has been facilitated by the development of novel radar ...

Multipath ghost elimination for throughâwall radar imaging
IET Radar, Sonar & Navigation, 2016In through-wall radar imaging, the multipath echoes caused by specular reflections at interior walls of an enclosed room will lead to multipath ghosts in the resulting image.

Photonics-based radar with a photonic de-chirp receiver has the advantages of broadband operation and real-time signal processing, but it suffers from interference from image frequencies and other undesired frequency-mixing components, due to single ...

Synthetic aperture radar (SAR) and inverse synthetic aperture radar (ISAR) are referred to in literature as imaging radars because of their ability to reconstruct electro-magnetic (e.m.) images of natural and man-made objects by coherently processing the echoes coming from the targets at different aspect angles.

Using range and Doppler information to produce radar images is a technique used in such diverse fields as air-to-ground imaging of objects, terrain, and oceans and ground-to-air imaging of aircraft, space objects, and planets. A review of the range-Doppler technique is presented along with a description of radar imaging forms including details of data ...

Radar as a coherent imager is physically based on the wave equations that govern the behavior of wave-targets interactions through the process of radiation, transmission, propagation, and reflection/refraction. This chapter briefly introduces the stochastic wave equations at a minimum but sufficient level to serve as fundamentals of radar imaging ...

Spaceborne radars are able to image ocean surface features, providing useful information on a global basis regardless of the weather conditions (especially clouds), both during the day and at night. This article explains this capability and provides illustrations of some of the results obtained.
