| 摘要 | Acoustic detection technology has disadvantages, such as short forecasting time in monitoring low-altitude flying targets. Based on the principle that the speed of precursor waves is greater than the speed of sound, this article proposes a complete method for forecasting low-altitude flying targets using precursor seismic waves. First, ray-tracing models of 3-D single-frequency helicopters and broadband-signal aircraft were established based on the attenuation law of precursor wave propagation. Then, the Doppler frequency shift equation of precursor wave is derived and found that the frequency width of precursor wave varies less. In addition, with the increase of distance, the precursor wave correlation detection ability shows a pattern of increasing and then decreasing. Then, an arrival-pickup algorithm is proposed for precursor waves based on multitemporal window determination. Under the experimental conditions, the use of properly developed precursor waves with other trace correlation detection is able to forecast low-altitude flying targets of at least about 6 km. The simulation results illustrate the feasibility and validity of this study. © 1963-2012 IEEE. |
