Abstract:
1. An active radar system, comprising: at least two transmit antennas configured to transmit radiation to a scene as at least a first transmit signal and at least a second transmit signal, respectively, each transmit signal comprising a series of frequency modulated pulses; at least one receive antenna configured to receive radiation from said scene as at least one receive signal; a controller configured to control at least one of said at least two transmit antennas such that a first transmission of the at least first transmit signal and the at least second transmit signal is initiated with a time offset, such that the time offset is controlled to be larger than a time delay between the transmission of the at least first transmit signal and reception of radiation of said at least first transmit signal received by said at least one receive antenna, and to be smaller than a time duration of a complete frequency modulated pulse of said at least first transmit signal; and signal analyser configured to analyse said at least one receive signal to determine the time delay, wherein said controller is further configured to control the time offset for at least a subsequently initiated transmission of said at least first transmit signal and said at least second transmit signal based on the determined time delay.
