Analysis of echo signal modulation characteristic parameters on aerial and space targets
Based on the scattering characteristic, the comparison of RCS (radar cross-section) at different positions of a target in the same direction of incidence can be obtained first by extruding or deleting part of the entity. A simulation method of aerial&space targets echo characteristics (A&STE...

| description | Based on the scattering characteristic, the comparison of RCS (radar cross-section) at different positions of a target in the same direction of incidence can be obtained first by extruding or deleting part of the entity. A simulation method of aerial&space targets echo characteristics (A&STEC) is proposed that is universal to aerial and space targets. We utilize a fixed-wing UAV (unmanned aerial vehicle) and typical missiles in simulation. The echo signal modulation characteristic parameters are calculated theoretically by the atmospheric attenuation model, the finite element method and a MUMPS solver. The verification simulations show that this method can analyze the influence of the target shape, incident direction, detection position and detection frequency on echo waveform, intensity and energy distribution. The results show that the profile of echo waveform can invert the general shape of the target. The relationship between time and intensity can determine whether the target is moving towards or away from the detector in addition. These conclusions can provide a reference for the ballistic missile target tracking and the defense against UVA intrusion in theory. |
