A method of compressing digital signal data obtained from a signal is described. The method includes: receiving digital signal data associated with a signal and/or generating digital signal data based on a signal; transforming the digital signal data into a transform domain, thereby generating transformed digital signal data; determining at least one characteristic parameter based on the transformed digital signal data by an artificial intelligence circuit; detecting and/or classifying at least one wanted signal portion based on the at least one characteristic parameter by the artificial intelligence circuit; and storing only a subset of the digital signal data that is associated with the at least one wanted signal portion. Further, a signal compressor circuit for compressing digital signal data obtained from a signal and a computer program are described.

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. The display module illustrates the symbol generated in the two-dimensional representation provided by the graphical user interface.
