DOUBLE-TARGET-SURFACE MULTI-LATTICE DISTRIBUTED ACOUSTIC PRECISION TARGET AND WARHEAD SHOCK WAVE MACH ANGLE TESTING METHOD

The invention relates to the technical field of target range multi-parameter measurement, and particularly relates to a double-target-surface multi-lattice acoustic precision target and a warhead shock wave Mach angle testing method. The double-target-surface multi-lattice acoustic precision target comprises a front target surface and a rear target surface which are vertically arranged and parallel to each other, a rear target frame, a shock wave detector array, a shock wave signal processing circuit and a data processing upper computer, a shock wave detector E is arranged on the front side surface of the front target surface, and the shock wave detector array arranged in a regular polygon or circular array manner is arranged on the rear target surface corresponding to the front target surface in the direction perpendicular to the front target surface; and the shock wave detector array is composed of n shock wave detection units and used for collecting shock wave signals, transmitted to each detection unit, of shock waves in the process that a warhead is perpendicularly incident on the target surface. According to the double-target-surface multi-lattice acoustic precision target and the warhead shock wave Mach angle testing method, the problem of multi-parameter measurement of an existing target range can be solved under the condition that high precision is guaranteed, meanwhile, the vacancy that application of an existing warhead shock wave Mach angle measurement technology is immature is made up, the flight speed, target landing coordinates and the warhead shock wave Mach angle of the warhead can be obtained, and the test precision is high.
