As evidenced by recent literature [1–4] and by the theme of a recent radar conference, 2001: Radar’s Odyssey into Space [5], there is currently much interest in moving radar technology onto spaceborne platforms. The advantages of moving radar into space are numerous [3, 6–7]. First, spaceborne radars provide global coverage, as opposed to airborne radars that are limited by airspace restriction...

Australia has conducted research into over-the-horizon radar (OTHR) for almost sixty years. Early programs focused exclusively on military capabilities, such as the detection of aircraft, missiles and ships, but in 1974 a team was formed to design a new OTHR for which a remote sensing mission was proposed. Oceanic wind mapping experiments in 1977-78 yielded promising results so remote sensing b...

Logan Scott is a consultant specializing in radio frequency signal processing and waveform design for communications, navigation, radar, and emitter location. He has more than 25 years of military GPS systems engineering experience. As a senior member of the technical staff at Texas Instruments, he pioneered approaches for building high-performance, jammingresistant digital receivers using larg...

Development teams apply various techniques to improve software reliability, such as veri cation and validation, reengineering, extra reviews, additional testing, and strategic assignment of personnel. Due to resource and time constraints, one must often target reliability enhancement activities to high-risk modules. Software quality models predict which modules should be targeted. This position...

UWB technology is advancing rapidly because of its potential to have high data rates and very low radiation power. In recent years UWB technology has been used in the areas of, sensing, radar and military communications [1]. In February 2002, the Federal Communications Commission (FCC) of the United States issued a report that UWB could be used for wireless data Communications [2]. Since then, ...

The Defence Science and Technology Organisation of Australia undertakes the role of evaluating proposals for the acquisition and upgrade of military systems. Simulation is increasingly employed as a means of assessing military effectiveness and systems performance. This might be because the systems concerned exist only on paper or because there are too many variables affecting the system’s perf...

The gradual transition of analog signal processing to the digital domain in radar and radio systems has led to advancements in beamforming techniques and, consequently, to new applications. The ability to steer beams digitally with great precision has radically changed the future of commercial and military radar system design. Adaptive beamforming algorithms have pushed the signal processing wo...

Micro-Doppler signatures provide unique information about properties of the target. These micro-Doppler features can be used for real time target recognition in military applications and surveillance operations. In this paper, we present Gabor-Wigner transform for extracting micro-Doppler features from the radar returns. The effectiveness of the GaborWigner transform in extracting micro-Doppler...

There are many medical, military and industrial digital image processing applications which as part of their fundamental operation depend upon the extraction of a phase signal from their input image. Examples of such applications are magnetic resonance imaging (MRI), synthetic aperture radar (SAR), fringe pattern analysis, tomography and spectroscopy. These systems use modern and mature algorit...
