摘要:
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 (LO1), at least one second local oscillator unit (2-2, . . . 2-N, 122, 222) for generating at least one second radio frequency carrier frequency signal (LO2), a switching device (3, 103, 203) for passing on one of the radio frequency carrier frequency signals (LO1, LO2) 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 (f1, . . . f8) and length (Tp) in a manner dependent on the control signal (CTR).
