Description: The effect of non-stable carrier frequency of sensing signals on inter-period correlation of passive jamming was considered. The ways of radio-impulses non-stable carrier frequency reducing affect on efficiency of movable target selection system were determined. The analysis of adaptive filter-corrector required operation accuracy when high efficiency operation of movable targets selection system achieved was conducted. The recommendations about structure modification of radar transmitter-receiver duct are given. Proposed variant of protected from passive jamming radar structure with low-stable generator instruments.
Keywords: low-stable generator instruments, adaptive filter-corrector, movable targets selection system
