Zusammenfassung: | The invention provides a low observability boosting-gliding trajectory target detection tracking method under a tilt distance ambiguity condition, belongs to the field of near space hypersonic velocity target detection tracking, and configures an alternating pulse repetition frequency model for radar ranging; defining an extended non-coherent accumulation model in a distance-time plane for target detection; configuring an S-type recursive energy tracking model for target tracking; and designing a recursive energy filter, and updating through recursive energy, so that target tracking is always kept under the condition of a high signal-to-noise ratio, and a target track is obtained by using a filtering algorithm. According to the method, the pulse repetition frequency in the same sampling period is designed to be a fixed value, so that the pulse repetition frequency has enough energy for coherent accumulation detection; and pulse repetition frequencies in different sampling cycles are designed to be alternately |
