TLDR
In this paper, the authors outline the special considerations that characterize the design of an UWB radar for the detection of low altitude missiles over the sea and discuss the factors which enter into the choice of frequency, and the selection of the transmitter, antenna, and receiver.Abstract:
The paper outlines the special considerations that characterize the design of an UWB radar for the detection of low altitude missiles over the sea. It discusses the factors which enter into the choice of frequency, and the selection of the transmitter, antenna, and receiver. Reviewed are signal processing issues concerning detection of UWB signals in noise and clutter, non-Doppler MTI based on the pulse-to-pulse change in range due to target motion, measurement of target height based on multipath time delay, and target recognition. The chief limitation of UWB radar that must be overcome before applications are viable is its poor electromagnetic compatibility (EMC).read more

The Microwave Power Module: a 'supercomponent' for radar transmitters
TL;DR: The MPM concept, program, and preliminary conclusions derived from several generic radar system point designs are presented in which the MPM is, at the least, a viable alternative to existing and projected technologies and, at most, represents a point of departure for exciting radar system enhancements.

High-power waveform generation using photoconductive switches
TL;DR: In the nanosecond time regime gallium arsenide photoconductive devices are nearly ideal circuit elements for the generation of wideband high-power waveforms as discussed by the authors, and the ability to activate these devices in an avalanche mode further enhances their utility since semiconductor lasers with nanojoule-range pulsed output can enable turn-on.
