Test Equipment and Techniques for Airborne-Radar Field Maintenance

The scope of this paper covers. the various testing methods, techniques, and equipment that are used for the field maintenance of airborne-radar systems. Techniques used in the measurement of frequency, power, and receiver sensitivity are outlined, as well as measurements of performance characteristics peculiar to airborne-radar equipment. The specially designed instruments required for field maintenance and the unique procedures devised to accomplish the measurement of radar performance characteristics for optimum radar performance are described. Special emphasis is directed to the application of special test equipment, such as echo boxes, directional couplers, and signal generators, for maintenance of microwave radar equipment.
