摘　　要：Dear editor,Radar waveform design with desired correlation properties has received considerable attention because of its performance improvement in the detection of a weak target[1,2].Moreover,owing to the increasing demand for access a wide radio frequency spectrum,coexistence among radar and telecommunication systems are currently instrumental in solving the spectrum-congestion problem[2].Based on spectrum sensing in cognitive radar[3],several approaches have been developed[4,5]to form radar signals with an appropriate frequency allocation,while minimizing its autocorrelation sidelobes.However,these studies have only focused on the single waveform design and did not consider the limitation of the available number of bits in the digital signal generators,likely resulting in performance deterioration.
