Description

technical field [0001] The invention belongs to the technical field of radar signal simulation testing, and in particular relates to a radar fault simulation technology. Background technique [0002] Radar equipment is large-scale, complex in structure, and multi-functional. The role and coupling relationship between functional units are getting stronger and stronger, and the transmission of fault modes is becoming more and more complicated. The current fault injection method is applied to the testability of new active phased array radars. During the test, it was severely restricted. The current fault injection relies on instrumentation equipment, and it cannot solve the fault injection problems of active phased array radar arrays, high-speed digital circuit modules, and airborne electronic equipment FC bus for various failure modes of radar equipment. The problem of high risk of fault injection and low efficiency of fault injection. Contents of the invention [0003] In...
