摘要
The wide application of helicopters in military missions challenges present radar systems. It is very urgent to solve the problem of detecting low-altitude, slow-speed and hovering helicopters. By the use of Radar Target Backscattering Simulation Software and through many flight mode and research mode experiments with the U.S.-made helicopter AH-64 as an example, a detailed analysis of helicopter echo time, frequency domain and time-frequency distribution characteristics is made. Finally according to these features, a tentative plan to detect hovering helicopters is proposed.
