Study on the algorithm of Doppler resolution of signals resembling rectangular pulses

The calculation for the nominal velocity resolution parameter and Doppler resolution constant of a signal made up of several rectangular pulses according to the definition is complex, especially when it is a multiple-period signal. The paper put forward an algorithm to search for the row of the ambiguity function matrix where the "half power" point exists and then solves the problem mentioned above. The result of the signal in single periods is used to calculate the Doppler resolution constant of "sync-plus-white" signal in several periods and the integral of high power terms of the envelop function is simplified, avoiding complicated and duplicated calculations and raising the efficiency.
