Abstract

Considered a way to increase vibration resistance on-Board systems of the aircraft. It is proposed to solve the problem of conservation of their functional reliability to use circuit methods, dimly lit, with regard to the effects of vibration, known to the authors in the literature. Based on the selected as the object of analysis of the radar receiver detection is defined by its cascades that give the largest contribution to the decrease in vibration resistance – antenna device, and to a lesser extent the mixer and the local oscillator. The parameters of fluctuations of the electrical parameters of antennas,mixers, and local oscillators. For analysis the proposedreview of the parts of a receiving device in the form of a linear two-port. Find a way of bringing the effects of modulating interference in a view that allows you to use methods of dealing with fluctuation noise. In this paper considered schematic way to improve vibration resistance by changing the transfer function of the optimumfilter and threshold decision. The described results allow to draw the attention of developers on-Board equipment on such an important component of the methods of protection against mechanical impacts as the response of the instrument to vibrate at a schematic and system design.

Key words

vibration, fibrosum, receiver detection, optimal filtering, oligopsony models.
