ABSTRACT We study the case of a moving target that is observed from a ground radar station. The target has relatively slow yaw angle and slow rotation angle. The coordinates of each reflector is studied and estimated from only one viewing ground station and for relatively short period of one second. The compensated range and the Doppler shift were interpreted as phase modulated (PM) signals. Bessel function expansion was used to find, for each reflector, an estimate for the unknowns: (1) yaw frequency, (2) rotation frequency, (3) x coordinate, (4) y coordinate, and (5) z coordinate. Only range data is used for the estimation. The unique Bessel functions parameters are guaranteed using the location of the peak of the spectrum of the signal. The cross range or Doppler data could be used to verify and adjust the estimated values. The approach was applied to simulated 3D inverse synthetic aperture radar (ISAR) imaging. |
