TARGET SIMULATOR Russian patent published in 1999 - IPC

FIELD: radar equipment, in particular, for testing and checking radar stations indoors. SUBSTANCE: device has anechoic chamber, tested radar station, antenna of tested radar station, which is mounted in hole on wall of anechoic chamber, simulator of target echo, or sequence of simulators for simultaneous simulation of several targets. In addition device has emitter or sequence of emitters, each of which is connected to its own echo generator, two spherical antennas and cables for microwave transmission. Spherical surfaces of antennas are identical and are designed as horn array. Each horn of first antenna is connected to corresponding horn of second antenna using transmission cables, which electric lengths are equal. Emitters are located on paraxial focal surface of second spherical antenna. Horns of first spherical antenna are directed towards antenna of radar station under investigation. This antenna is located in near range of radar station and oriented so that center of its sphere coincides with center of antenna of radar station. EFFECT: increased range of target imitation in elevation plane, causing increased field of device application. 1 dwg
