摘要： An RCS reduction surface for reducing a radar cross section of an object is described. The RCS reduction surface comprises at least one absorber portion, wherein the absorber portion is configured to absorb radar waves. The RCS reduction surface further comprises at least one reflecting portion, wherein the reflecting portion is configured to reflect radar waves. A first plane being associated with a top surface of the absorber portion and a second plane being associated with a top surface of the reflecting portion are spaced from each other by a predefined distance. The predefined distance is configured such that radar waves with a predefined wavelength range that are reflected at the absorber portion and at the surface of the reflecting portion interfere destructively with each other. Further, an RCS reduction member and a radar test system are described.

摘要： A radar target simulation system for simulating at least one radar target is disclosed. The radar target simulation system includes a processing circuit and an antenna array that is connected with the processing circuit. The antenna array is configured to receive a radar signal from a device under test, thereby generating an input signal. The processing circuit is configured to receive the input signal generated by the antenna array. The processing circuit is configured to simulate the at least one radar target based on the input signal. The processing circuit further is configured to simulate at least one additional event, wherein the at least one additional event is associated with at least one of the at least one radar target and an environment of the at least one radar target. The processing circuit is configured to generate an output signal for the antenna array based on the simulation of the at least one radar target and based on the simulation of the at least one additional event. Moreover, a radar target simulation method is described.

摘要： A LIDAR target simulator for testing a LIDAR device is described. The LIDAR target simulator includes a screen, a light impinging determination module, a control and/or analysis circuit and a response generation module. The light impinging determination module is configured to determine the location of impinging light on the screen and to forward information concerning the location determined to the control and/or analysis circuit. The control and/or analysis circuit is configured to process the information concerning the location determined by the light impinging determination module and to determine a response based on a target scenario applied. The control and/or analysis circuit is further configured to control the response generation module in accordance with the response determined. The response generation module is configured to generate a diffuse response signal to be received by the LIDAR device. Further, a LIDAR testing system and a method of testing a LIDAR device are described.

摘要： A radar target simulator front end, configured to simulate at least one radar target for testing a radar device under test is provided. The radar target simulator front end comprises at least two antenna units, arranged along a first angle under investigation. The at least two antenna units are configured to be selectively activated and deactivated. Whereby each antenna unit of the at least two antenna units generates a simulated radar target along the first angle under investigation, when activated.
