Abstract:

In order to clarify a defensive party's understanding of the performance of incoming near space hypersonic target and improve the existing missile defense strategy, the early warning detection characteristics between hypersonic target and ballistic missile are compared and analyzed. By establishing a target motion model, a infrared detection model, and a radar detection model with moderate particle size, the influence of the flying altitude and lateral maneuverability of the two kinds of targets on the ground-based early warning system and the detectability of infrared radiation are analyzed in detail and quantitatively under the same simulation conditions. Analysis results show that under the same downrange, lower flying height and stronger maneuverability of the hypersonic target make it more difficult for the radar to search and capture, but the target's strong infrared radiation intensity makes the stable early warning detection time for the target longer.

Key words: defensive party, hypersonic target, ballistic missile, performance model, search capture, early warning time
