摘要

The alternate transmission method ofM-sequence pulse compression has beenproposed to extend the measurable distance. Thecodes selection is an effect on the interferencenoises characteristics of alternate transmissionmethod. In the convolution and the experimentsignals, the maximum amplitude of interferencenoises is increased by overlapping of the impulseresponse of the loudspeaker. Moreover, themaximum amplitude of the convolution and theexperiment conditions are slightly differentvalues. Therefore, the convolution signal can beapplied to be search the best signal for theexperiment.
