A radar wave imaging device (10) comprises a radar transmitter unit (18) having at least one radar transmit antenna (20) for transmitting radar waves towards a scene and a radar receiving unit (22) including a plurality of radar receiver members (24) that are arranged as a two-dimensional array, for receiving reflected radar waves. The radar receiving unit (22) includes an imaging radar optics unit (32) for imaging at least a portion of a scene onto at least a portion of the two-dimensional array of radar receiver members (24).The imaging radar optics unit (32) comprises at least a first radarlens (36) that is arranged between the radar receiver members (24) and the scene. The radar receiver members (24) are arranged in direct contact to a surface of the first radar lens (36) that is facing away from the scene.
