UWB Radar RF Front-End to Mitigate Impacts on EESS and Radio Astronomy

A novel UWB short-range radar (SRR) which effectively mitigates its impacts on radio services using the restricted band such as radio astronomy or Earth Exploring Satellite Service is introduced. The essential components, a burst oscillator generating no carrier leak, and antennas with notch-filtering function are presented in detail. Other key MMICs, such as a high-speed square-law detector, variable gain LNA, a sample-hold circuit, etc. are also described with the performances of the SRR
