In order to solve the problem of antagonizing anti-radiation weapon, a tracking method based on adaptive pulse interval is proposed for fire-control radar. First, an improved signal model for fire control radar is proposed after the monopulse signal expression is given. Then, the principle of adaptively choosing pulse interval based on tracking precision is(More)
PRC-CW radar is mainly used to detect moving targets on ground. Ground clutter heaves fiercely, and its distribution is complex, which makes it difficult to detect targets correctly from time domain. The characteristics of moving targets and ground clutter differ in frequency domain. And the spectrum of targets may change with time, so, this paper designs(More)
A modeling method for radar signal receiver channel is proposed under the situation that part of the mechanism is unknown. Firstly, the traditional identification methods including Levy least square, pulse response and frequency-domain multiply are analyzed. The experiments show that those methods are hard to get the accurate model of high order radar(More)
By analysis of a practical case, this paper built the maintenance cost model of the complex item with compound failure modes, one of which has characteristic of potential failure. The procedures and methods of the modelling are also discussed in detail. At last, the practicability and validity of the model outputs are validated by way of numerical examples.(More)
