In view of the demand for full size large stealth target's RCS measurement, the outdoor field RCS measurement, especially the direct signal processing technology, is also put forward higher requirements. In offsite relative calibration, the calibrator can be exactly equal to the reference branch coherent measurement system and how to make use of this characteristic will directly affect the precision...
The precession angle is one of the important characteristics of radar target recognition. Aiming at the existing problem of continuous observation time and the biggish error estimation existing in the radar target feature extraction methods, this paper presents the radar multi-view fusion precession feature extraction method. Based on multiple radar cone target precession model, the method uses only...
Complex resonance frequencies contained in target's late-time transient responses are independent of target aspect and radar signal's polarization only relate to inherent characteristic, such as, size and shape of the target. This paper introduced the Prony method and MPM, and make comparisons between them by using the reconstructed late time response to estimate the anti-noise performance. Then MPM...
In order to estimate the precession and structural parameters of the cone-shaped target, a new method based on the profile length is proposed. The precession model of the cone-shaped is established firstly, then the profile length expressions of the cone-shaped target are derived. The relation between precession and structural parameters and profile length are investigated, and the expression to estimate...
In the process of actual radar observations, the influence of noise could inevitably generates breakpoint and induces defocusing in the time-frequency image of micro-motion target obtained by narrowband data, which leads to the inaccuracy of micro-motion feature extraction. In this paper, the frequency diversity is utilized in feature extraction of micro-motion time-frequency image. For stepped frequency...
Frequency variation could cause resonance region's Radar Cross Section (RCS) changes in oscillation, which always has a couple of resonant peaks, and the resonant frequency is a useful index that can help target detection and tracking. This paper, which is based on calculated data, analyzes the relationship between the resonant frequency and a series factors, including the attitude angle, size, volume,...
