“…To maintain energy storage requirements on the re-entry body, thus increasing payload capacity, spin stabilization is normally employed to maintain attitude through the coast phase of the mission [1]. The telemetered data of the FIREFLY ballistic mission simulation on 29th March 1990 [2] indicated that the spin rate of a cone shaped balloon was 0.85Hz.…”

The spinning motion of a ballistic missile (BM) induces periodic frequency modulations on the returned radar signal. This 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 then extracts the micro-Doppler modulation frequency through analysis of the periodic structure of the resulting spectrogram (short time Fourier Transform (STFT)) -i.e., the time-frequency distribution (TFD). In order to be used for BM target recognition we implemented a data-dependent optimal window length for the STFT. We treated the resultant TFD as an image and then used the 2-D DFT/FFT for feature extraction. Experimental results illustrate the validity of the proposed method.

“…The multi-fin BMs usually spin in coast phase (above the atmosphere) for reasons of attitude control [1]. The spinning motion induces a micro-Doppler modulation (i.e., a special signature for missile recognition) in the frequency spectrum of the radar echo, that appears as a periodic pattern in the time-frequency distribution (TFD).…”

“…Space targets and ballistic targets usually spin for attitude control, precession will occur if there is a latitudinal disturbance on targets' spinning motion [1] . Therefore, precession is a typical micro motion for space targets and ballistic targets, whose dynamic echo is the basis to analyze the characteristics of these targets.…”

Dynamic echo is the basis to analyze and discriminate the features of precession targets, but it is difficult to acquire the outfield data with small cost. In this paper, precession model of a general target is built, and the attitude formulas of elevation and azimuth are derived respectively. On the basis of the static electromagnetic scattering data, a scheme is proposed to simulate the dynamic echo of an arbitrary precession target by using the quasi-static method. Its validity is verified by the experiment results, and the RCS sequences and micro-Doppler signatures of two representative targets are analyzed based on the simulated echo.

“…Introduction: Since warheads are usually spin-stabilised in the ballistic midcourse phase [1], precession will occur if there is a latitudinal disturbance. The precession, which is a typical micro-motion of the warhead, will generate frequency modulations of the returned signal in addition to the Doppler shift caused by the warhead's translational motion.…”

To investigate micro-Doppler signatures of precession for a warhead with empennages, the model of precession is built and mathematical formulas of a micro-Doppler induced by different scattering centres are derived. The relationship between the micro-Doppler appearing frequency of empennages and micro-motion frequencies is first acquired, then two important precession features, namely coning frequency and spinning frequency, are extracted based on the micro-Doppler. Simulation results are provided to demonstrate the validity of the proposed method.
