Frequency pattern generator ( 1, 101, 201 ) for generating frequency pulses, said generator having a first local oscillator unit ( 2 - 1, 121, 221 ) for generating a first radio frequency carrier frequency signal (LO 1 ), at least one second local oscillator unit ( 2 - 2, . . . 2 -N, 122, 222 ) for generating at least one second radio frequency carrier frequency signal (LO 2 ), a switching device ( 3, 103, 203 ) for passing on one of the radio frequency carrier frequency signals (LO 1 , LO 2 ) or a zero signal (DC) in a manner dependent on a control signal (CTR), and a mixing stage ( 9, 109, 209, 212, 309 ) for mixing the signal (LO) that has been passed on by the switching device ( 3, 103, 203 ) with a mixing frequency signal (LF) to form a pulsed output signal (RFOUT), the pulsed output signal (RFOUT) having frequency pulses at a respective frequency (f 1 , . . . f 8 ) and length (Tp) in a manner dependent on the control signal (CTR).
