Other AbstractThis paper analyzes some major parameters affect ing the perfo rmance of digital Chirp implemen ted by wavefo rmsto rage DDS app roach.At the same time,compares the advan tages and disadvan tages betw een the w avefo rm 2sto rage DDS app roach and ano ther DDS app roach of phase accumu lat ion.Compu ter simu lat ion s w ith MA TLAB/S IIMUL IN K show that, samp ling frequency,resolution of the Digital-to-analog-converter,low pass f ilter and I/Q modu lato r affect the output Chirp spect rum in differen taspects.The developed sof tw are based on MA TLABS IIMUL/INK can p rovide an analyzing, design and optimization platform for DDS digital chirp.
