Abstract
There is described a radar system (100) and a corresponding method, the radar system (100) comprising i) a control unit (110), configured for generating a code (C) comprising a sequence of code symbols (211), wherein generating the code (C) comprises randomly selecting a plurality of code symbols (211) from a code symbol pool (310) comprising a plurality of code symbols (211), ii) a transmitter (120), configured for generating a signal (S) from the code (C), and further configured for transmitting the signal (S), iii) a receiver (130), configured for receiving an echo (E) of the signal (S), and iii) a correlator (140), configured for correlating each code symbol of the code (C′) of the received echo (E) of the signal (S) to a corresponding symbol template (R) associated with the correlator (140); wherein the radar system (100) is further configured for synchronizing the symbol template (R) to the code (C) of the signal (S). There is further described a method of using a sequence of randomly selected code symbols (211) in a radar application, in particular an UWB-based radar application, to prevent replay attacks.
