In the paper the results of a computer survey of the uniform phase manipulated signals with great structural complexity and small lose in the signal-to-noise ratio after processing with mismatched filters are presented. These results can be used in the development of radars with high resistance to hostile radio-electronic environment and ability for discovering and resolution of small objects.

In the paper an algorithm for synthesis of pseudo-noise signals with high structural complexity is presented. It is based on the possibility the elements of the finite algebraic fields to be generated by means of a linear recurring sequence with maximal length. The algorithm can be used in the development of communication systems with high resistance to hostile radio-electronic environment.

The report justifies the view that despite the apparent trend of warming and drought in recent years, there is an increasing frequency of extreme weather and climatic events (rainfall), which cause extensive damage to infrastructure and high costs to the economy and society. Therefore, to improve the performance and effectiveness of State bodies engaged in the prevention or eradication of harmful effects in emergency situations, it is necessary to make scientifically sound estimates of the frequency of intense precipitation over the next few years. Solving this important practical tasks is possible through the development of a statistical model of the intensity of the precipitation.
