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
