An automatic SAR-GMTI algorithm based on DPCA

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
An automatic DPCA technique is presented for SAR Ground Moving Target Indication (GMTI). We note that there exists a shift and a phase difference between the images from two channels. Therefore, SAR-GMTI can be implemented in the following steps: Image registration, phase compensation, image subtraction, and CFAR detection.

Concept and performance analysis of Melissa MIMO GMTI

2015 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2015
One of the most important task for a radar system in the security domain is to discriminate a potential moving target from the clutter background, especially when the Signal-to-Clutter Ratio (SCR) is low. This document hence describes a new algorithm for improving the detection of a potential moving target when a Ground Based (GB) MIMO SAR is adopted ...

Effect of ambiguities on GMTI radar

2002 International Radar Conference (Radar 2002), 2002
We focus on the effect of range and Doppler ambiguities on the ability to detect slow moving targets by STAP radar. This work has been conducted in the context of international projects such as SOSTAR and AMSAR.The detection of moving targets by a moving radar (air- or spaceborne) is seriously degraded by strong clutter returns.

Road Map Extraction using GMTI Tracking

2006 9th International Conference on Information Fusion, 2006
For analyzing dynamic scenarios with many ground moving vehicles, airborne Ground Moving Target Indicator (GMTI) radar is well-suited due to its wide-area, all-weather, day/night, and real time capabilities. The generation of GMTI tracks from these data is the backbone for producing a "recognized ground picture" as well as for analyzing traffic flows ...

The applicability of GMTI MIMO Radar

2010 Conference Record of the Forty Fourth Asilomar Conference on Signals, Systems and Computers, 2010
MIMO Radar has been proposed as a technique for improving the Minimum Detectable Velocity (MDV) performance of airborne radar systems. However, the increased pulse repetition frequency associated with waveform multiplexing techniques used in GMTI MIMO Radar increases the amount of range ambiguous clutter the radar must suppress, reducing the amount of ...

Bi- and monostatic SAR-GMTI

2017
This chapter presents a novel simultaneous monostatic and bistatic ground moving target indication (GMTI) mode for improved target detection and imaging capability. The mode uses an airborne multichannel radar system and a stationary transmitter. Both systems transmit simultaneously on adjacent frequency bands, and the airborne multichannel system ...

Circular-shift transmission MIMO GMTI radar

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
The coherence and blind velocity are two important questions in multiple-input multiple-output (MIMO) radar ground moving target indication (GMTI). Multi-frequency signal is an effective way to solve the blind velocity problem, and multi-frequency signals are usually transmitted by MIMO radar. However, by this way the coherence is lost.

A compressed sensing based method for SAR GMTI

2017 4th International Conference on Systems and Informatics (ICSAI), 2017
This paper proposes a synthetic aperture radar (SAR) imaging method based on compressed sensing for ground moving target identification (GMTI). Since the targets are sparse or compressible in the area of interest, it is sufficient to reconstruct the image by only sampling a small number of receiving data randomly.

Bistatic GMTI experiment for airborne platforms

Record of the IEEE 2000 International Radar Conference [Cat. No. 00CH37037], 2002
The concept of bistatic ground moving target indicator BGMTI is presented here. Monostatic GMTI radars use separate modes for ground movers whose Doppler does and does not allow separation of the target return from ground clutter using frequency processing. Bistatic flight scenarios that minimize Doppler spreading in the vicinity of a designated target

JointSTARS and GMTI: past, present and future

IEEE Transactions on Aerospace and Electronic Systems, 1999
The concept of airborne surveillance of enemy ground forces with a Ground Moving Target Indicator [now called GMTI] radar capable of detecting moving ground vehicles and helicopters was proposed in 1968 and resulted in a DoD program to realize its potential.
