Analyzing the measurements of Radar Cross Section (RCS) characteristics is an effective and important method in the non-cooperative target detection, such as the ballistic missiles. However we should not ignore target fluctuation and should obtain dynamic RCS measurements for the targets over appropriate aspect angle regions. In this paper the geometric model of a precessing conical warhead in flight...
In order to estimate a ballistic missile precession frequency, which is an important feature parameter in ballistic target recognition, we firstly establish the dynamic Radar Cross Section (RCS) signal model for a conical ballistic missile warhead with precession motion. Scintillation which is an important factor that cannot be ignored in radar measurement is taken into account in the model establishment,...
The spinning motion of a ballistic missile (BM), which is a kind of micro-Doppler motion, induces additional frequency modulation on the returned radar signal. This modulation period in frequency, called the micro-Doppler modulation frequency, is a stable and unique parameter in radar target recognition. This paper first establishes the radar signal model of the spinning missile during flight, and...
