摘要：Disclosed is a radar system capable of detecting near targets even in case ofusing discrete bands transmission signal. For this end, a discrete bands selection unit

selects discrete bands that meet the required radar parameters for detecting targetinformation. A discrete bands synthetic waveform generation unit suitably synthesizescenter frequency signals of the respective discrete bands on the time base so that thesignals for all of the discrete bands are transmitted within the transmission time of aparticular discrete band that requires the longest time among the signals for theselected discrete bands selected. Alternatively, the center frequency signal is generatedfor the particular band requiring the longest transmission time, while signals sweepingfrom lower limit frequencies to upper limit frequencies are generated during the

transmission time for the discrete bands other than the particular discrete band requiringthe longest transmission time. Subsequently, the signals for the respective discretebands are synthesized on the time base to generate discrete bands synthetic waveformsso that a discrete bands waveform storage unit stores them in a transmission signalbuffer.
