A NEW RADAR SYSTEM OPERATING IN THE FORWARD-SCATTER REGION

A new radar system is presented, which consists of one main radar and cooperative plural transponders. The transponders are integrated in th e respective retrodirective antennas which are arranged beyond the hor izon in such a manner as they surround the main radar. An algorithm fo r determining the three-dimensional target position is given. Computer simulations have been made for different target positions by assuming measurement errors. A target whose monostatic radar cross section is small or has been specially reduced by absorbing materials could be de tected by this system if it is properly constructed.
