Effect of Ship Swaying on Signal's Synthesis Efficiency of Antenna Array

It is important to analyse the effect of ship swaying in applying the technique of antenna array to space TTC ship.The relation model between range difference and ship swaying is presented when radar's antennas point to the same target.And the relation curves between speed of range difference and angles of antenna's azimuth and pitch are plotted.The synthesis efficiency and integral time of various frequencies' signals are analysed,which shows that signal's synthesis time is affected directly by speed of range difference,thus signal's synthesis efficiency is affected.It is also shown that the higher the frequency is,the lower the synthesis efficiency is.
