Description: This article analyzes the possibilities of determining the range of detection on a set of objectives with different heights of the effective scattering surface (primary radar), different characteristics of response-Pins (secondary radar) Tests radar in quantitative restriction of overflights. An the range of detection experimental-calculational method of determining the range of detection, based on calculations with calibration of some factors influencing on formings of diagram of orientation of aerial radar on the real position not known a priori, is offered, from data of experimental part of tests. Conditions for and limitations of the method. The validity of the method is shown by the example of radar interrogator IFF system 73E6.
Keywords: testing the radar, the zone of detection of radar, calculation of range of detection
