METHOD USING RADAR TO DETECT A KNOWN TARGET LIKELY TO BE POSITIONED AT APPROXIMATELY A GIVEN HEIGHT, NEAR OTHER TARGETS POSTIONED AT APPAOXIMATELY THE SAME HEIGHT

摘要

The present invention relates to a method of detection using a radar of a target capable of being disposed substantially at a given height h2 close to other targets are also arranged substantially at the height h2.une first phase of the detection of the target is made by carrying out a scanning in azimut.lorsque the target has been detected at a certain distance d 1 according to a certain angle of azimuth thetaaz, a second phase of detection is carried out according to the azimuth angle thetaaz and according to an angle of elevation thetael corresponding to that of an object situated to the said distance di to the height h2.la target is deemed to be detected if it is detected in the elevation angle thetael at a distance d substantially equal to the distance di.application: systems for assisting the takeoff and landing of aircraft
