Patent number: 11822769Abstract: A radar target simulator for simulating a radar target is disclosed. The radar target simulator comprises a display module and an input module via which a user of the radar target simulator is enabled to define a target to be simulated. The radar target simulator also comprises a processing module that is connected with the display module and the input module in a signal transmitting manner. The display module and the processing module together provide a graphical user interface for the user of the radar target simulator. The graphical user interface provides a two-dimensional representation of an at least two-dimensional space. The processing module receives at least one input signal from the input module based on an input of the user. The input of the user is associated with input coordinates in the two-dimensional representation. The processing module processes the at least one input signal, thereby generating a symbol of the target defined.Type: GrantFiled: June 12, 2020Date of Patent: November 21, 2023Assignee: Rohde & Schwarz GmbH & Co.
