Two Dimensional Array Imaging with Beam Steered Data

, 2013
This paper discusses different approaches used for millimeter wave imaging of two-dimensional objects. Imaging of a two dimensional object requires reflected wave data to be collected across two distinct dimensions.

Dual-functional microwave photonic system for concurrent radar and secure communication via radar signal masking [PDF]

arXiv
Integrating functions such as radar and communication into a single system is of great significance for the miniaturization and functional integration of future electronic warfare and 6G systems. Here, we show a dual-functional microwave photonic system for concurrent radar and secure communication.

Broadband circular interferometric millimetre-wave ISAR for threat detection [PDF]

Advances in Radio Science, 2007
To detect threats on a person's body surface the application of millimetre-waves is possible. In order to get a view of the person from all sides either the person has to be rotated standing on a turntable (Inverse Synthetic Aperture Radar, ISAR)

Indoor Synthetic Aperture Radar Measurements of Point-Like Targets Using a Wheeled Mobile Robot [PDF]

arXiv
Small, low-cost radar sensors offer a lighting independent sensing capability for indoor mobile robots that is useful for localization and mapping. Synthetic aperture radar (SAR) offers an attractive way to increase the angular resolution of small radar sensors for use on mobile robots to generate high-resolution maps of the indoor environment.

Cross-range scaling method of inverse synthetic aperture radar image based on discrete polynomial-phase transform

, 2015
The cross-range scaling of inverse synthetic aperture radar image depends on both the radar wavelength and the rotating angle of the target relative to the radar line-of-sight.

Inverse synthetic aperture radar imaging of targets with complex motion based on cubic Chirplet decomposition

IET Signal Processing, 2015
High resolution inverse synthetic aperture radar (ISAR) imaging of targets with complex motion is a main topic in the radar imaging domain. In fact, the traditional range-Doppler algorithm is not appropriate to generate a focused ISAR images because of ...

An Extended Virtual Aperture Imaging Model for Through-the-wall Sensing and Its Environmental Parameters Estimation [PDF]

, 2014
Through-the-wall imaging (TWI) radar has been given increasing attention in recent years. However, prior knowledge about environmental parameters, such as wall thickness and dielectric constant, and the standoff distance between an array and a wall, is ...
