Abstract: A threat analyzer receives threat data measured by detectors. The threat data characterizes a status of detected emissions for a corresponding detector. The threat analyzer analyzes the threat data to identify a geographic region that contains a threat to humans and stores the threat data and analyzed data in a database. The machine readable instructions also include a graphical user interface (GUI) generator that provides an interactive map with indicia that characterizes the analyzed threat data.

Abstract: A microstrip L-band bipolar dielectric resonator stabilized oscillator (DRO) devised in a moderate size (2'.times.5".times.3.6"), low-cost, reproducible circuit. Embedment of back to back varactors in the DRO provide voltage tuning for phase lock application without compromise of noise performance. Extremely low phase noise with a low l/f noise corner is achieved and the DRO is essentially constant in frequency and output power over temperature, all due to unique circuit configuration. An internal buffer amplifier and dc regulatory circuits provide a DRO that is insensitive to frequency pulling due to load changes and power supply voltage leads. New standards of performance are accomplished that permit simplified stalo configuration with lower phase noise.
