Development of a system to measure the response time of microwave survey instruments to rotating radar antenna patterns

The report describes the development of a system which simulates rotating radar fields in a controlled environment. The measured time variations of the field generated by a real, rotating radar antenna were first recorded using a computer controlled spectrum analyzer. The data acquired were then used to modulate a carrier wave field in the laboratory to simulate the rotating radar far-field. Finally, response of a thermocouple based microwave hazard survey meter to this field was measured.
