Radar sensor and method of operating a radar sensor

The invention relates to a radar sensor (101, 201, 401), comprising: a radar transmitting means (103) for transmitting radar radiation, a radar lens (105) for breaking the transmitted radar radiation, the radar transmit means (103) a plurality of arranged mutually offset radar transmitter (107, 109, 111, 113), wherein the radar transmitter (107, 109, 111, 113) each have a same directivity pattern (115) relative (to an optical axis 117) of the radar lens (105) comprise a controller (119) for controlling the radar transmit means (103), wherein the controller (119) is formed, the radar transmitter (107, 109, 111, 113) to activate independently of one another on or off, to the radar lens (105) from different positions relative to a focus of the radar lens (105 to be able to feed by means of radar radiation). The invention further relates to a method for operating the radar sensor (101, 201, 401). The invention further relates to a corresponding computer program.
