A Technique for the Stabilization of Burst Height in Radio Fuzes

Based on an analysis of factors affecting the dispersion of burst heightin existing continuous wave Doppler radio fuzes, features of their target signaland ways of their extraction are studied. The paper then describes a scheme oftechnique for the stabilization of burst height in radio fuzes. Circuit design,adjustment and testing of actual prototypes have been carried out. In order toachieve desired stabilization of the burst height. The scheme used applies bothphysical and mathematical transformations, viz. filtration, frequency compensationand differentiation. The target and interfering signals pass through 2 paths tooffset influences from compensating signal processing circuits, so as to reducefactors affecting the dispersion of burst height. A series of laboratory simulationtests has shown that the circuit possesses fine features in stabilization of theburst height, as well as abilities in antijamming from early burst, big pulsedelayed signals and peak signals. It also possesses the ability of targetrecognition. A practical signal processing circuit for the stabilization of burstheight is finally given.
