This paper is an attempt to present a short, unified discussion of the radar detection, parameter estimation, and multiple-signal resolution problems--mostly from a philosophical rather than a detailed mathematical point of view. The purpose is, hopefully, to make it possible in at least some limited sense to reason back from appropriate measures of ...

Challenges in detecting UAS with radar
2017 International Carnahan Conference on Security Technology (ICCST), 2017The recent proliferation of drones has contributed to the emergence of new threats in security applications. Because of their great agility and small size, UAS can be used for numerous missions and are very challenging to detect. Radar technology with its all-weather capability can play an important role in detecting UAS-based threats and in protecting

Radar Tomography For Cavities Detection
9th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 1996Preliminary tests on laboratory models have enabled us to provide some guidelines for traveltime ray tomography with GPR applied to civil engineering problems, specifically to find voids in pillars, walls and structures. The width of the Fresnel zone and the source and receiver locations are the limits to resolution capability. For crosshole geometry a

Multiresolution detection of coherent radar targets
IEEE Transactions on Image Processing, 1997We develop and investigate several novel multiresolution algorithms for detecting coherent radar targets embedded in clutter. These multiresolution detectors exploit the fact that prominent target scatterers interfere in a characteristic manner as resolution is changed, while multiresolution clutter signatures are random. We show, both on simulated and

PERMISSION has now been obtained to publish the fact that birds can reflect radio waves with sufficient strength to be detected by radar sets. Evidence of this was given to us in the summer of 1941 by Dr. E. S. Shire, then developing centimetric radar equipment at the Air Defence Research and Development, Establishment, Ministry of Supply. Confirmation

Abstract The theories of noise underwent a further change in the 1940s, as physicists, engineers, and mathematicians participated in military research during World War II. Whereas interwar research tackled the nature, causes, and properties of noise, the wartime research focused on the behavior of systems, machines, and devices in noisy ...

Radar photographs of thunderstorms and the Florida hurricane of September 1945 were shown to illustrate structure of those storms (see Fig. 1). The relation between radar echoes and the reflecting material in the storms was discussed. Previous research has shown the intensity of the return radiation, among other things, to be proportional to the number
