Nosmo Doppler Simulator

Abstract

A unit to simulate Doppler beating phenomena is described for use in air-borne radar training program. Unit amplitude modulates returned signals with a random frequency spectrum whose upper limit varies as the sine of the angle between the azimuth of the radiated beam and ground track of the aircraft. Practice in determination of drift angle is herewith made possible. The noise source employed is a miniature gas thyratron with a permanent magnet surrounding the tube to suppress inherent oscillations within the gas plasma. Pertinent data concerning the voltages throughout the circuit, wave forms, and power input are included in wave form charts.
