<p>PURPOSE:To measure a fine disturbing signal, an interference signal, and various directional disturbing signals by using plural auxiliary antennas which have higher directional characteristics than a radar antenna and also have radiation centers in mutually different azimuths. CONSTITUTION:Microwave signals received by the plural auxiliary antennas 101 - 10N are detected by disturbing signal detectors 201 - 20N to detect disturbing signals and measure the frequencies. Then the detection and measurement are monitored manually or automatically under the control of a controller 700, and if a disturbing signal or interference signal is detected over one channel, a signal is sent to a signal selector 500 and the signal of the detector of the detected channel is sent to a various-element measuring instrument 600, which analyzes various radio wave elements such as the arrival azimuth, pulse width, etc., of the signal and displays various measured elements on a display console panel together with a radar video. When plural disturbing waves or interference waves are received at the same time, the controller 70 switches the selector 500 in order to take measurements. Consequently, the disturbing waves can be detected with high sensitivity and various radio wave elements including the arrival azimuth in the total frequency band of the radar are measured.</p> |
