Recognition of a Hovering Helicopter
Zhao Hong · Systems engineering and electronics · 2002
This paper studies the characteristics of the echo from various hovering helicopters, and extracts the information of the maximal lineal velocity v\-\{ max \} and the period T\-p of echo scintillation. A recognition method using the above two kinds of information is proposed. The theoretical analysis and simulation experiments demonstrate the effectiveness of the method at low SNR.
