| Abstract: | This paper analyzes and studies the model and characteristics of echo from rotor of a low altitude hovering helicopter. A detection method is proposed based on this study, which includes time domain signal detection method and time/frequency domain combined signal detection method. It also utilizes the MATLAB to simulate and verify. The simulation results indicate that in L band, when suitable PRF and integration time are selected, the low altitude or super-low altitude flying or hovering helicopter can be detected. |
