Abstract :
The range-instantaneous-Doppler (RID) technique is a new method for ISAR image reconstruction recently proposed as an extension of the well-known range-Doppler (RD) technique. The RID makes use of the joint time-frequency transform (JTFT) instead of the classical Doppler spectral analysis. The purpose of this paper is to analytically and numerically show how the RID can be successfully applied to obtain ISAR images of a target accomplished by angular motions (pitch, roll and yaw). Specifically we analyze the behavior of the RID and the RD techniques when applied to the case of oscillating targets in rectilinear motion
