Abstract
A three-dimensional air space surveillance radar in which the radar receiver is connected to a target tracking means which stores target data and does extrapolation of target data for target trace formations, including a panoramic antenna which illuminates the entire elevation range to be covered and has a reception lobe at the elevation level which can be electronically or mechanically controlled such that a line air space scanning occurs during the course of normally sequence scanning programs. The line-shaped beam of the antenna is briefly interrupted in the invention from the normal reception lobe elevation angle when the tracker determines that a target echo is expected from a different elevation angle than that being scanned. During such scanning interrupt, the reception lobe is switched to the expected elevation angle of the target and in the invention, the data acquisition rate for the tracker is increased relative to known prior art three-dimensional surveillance radars which function on a strictly time sequential manner. The precision of the invention is retained and the invention is utilized in a tracker-equipped three-dimentional air space surveillance radar of high trace quality such as used, for example, in air defense radar.
