Self-sensing surface radar structure for hypersonic flight environment

The invention belongs to the technical field of surface radars, and particularly relates to a self-sensing surface radar structure for a hypersonic flight environment. A phase change/air cooling passive thermal insulation layer, a radiation array surface layer and a power division network layer all comprise antenna structures, each antenna structure comprises an antenna housing and a conformal array antenna, and each conformal array antenna comprises a conformal feed network, a first dielectric substrate, a grounding plate, a first metal frame, a second dielectric substrate, a second metal frame and a third dielectric substrate which are arranged in sequence. The second dielectric substrate is provided with an arched microstrip double-patch array, and the third dielectric substrate is provided with a conformal parasitic patch array; and aerogel is arranged between the first metal frame and the second dielectric substrate, between the second metal frame and the third dielectric substrate, and between the third
