| Abstract: | This paper analyzed the radar recognition ability of two kinds of air targets,i.e. helicopter and fixed-wing aircraft.The bispectrum features of the two kinds of targets were analyzed under the condition that the recognition ability was satisfied. Their differences were found,and a method for identifying the two kinds of targets was presented.This method has been proved to be efficient by testing the simulation datum of eighteen kinds of helicopters and fixed-wing aircrafts. |

| Keywords: | target identification radar time-on-target radar pulse repetition frequency bispectrum feature |
