Method using radar to detect a known target likely to be positioned at approximately a given height, near other targets positioned at approximately the same height

摘要

Using a radar to detect a known target likely to be positioned at approximately a predetermined height close to other targets, these other targets also being positioned at approximately the predetermined height. A first phase of detecting the known target is carried out by performing an azimuth scan. When the known target has been detected at a certain distance Di at a certain azimuth angle &thetas;az, a second detection phase is carried out at said azimuth angle &thetas;az and at an elevation angle &thetas;EL corresponding to that of an object situated at said distance Di at the predetermined height. The target is said to be detected if it is detected at the elevation angle &thetas;EL at a distance D approximately equal to the distance Di.
