Interconnecting of Ship Radars of Centimeter and Millimeter Wavelength Ranges

摘要

Complex application of radar information of the systems of different ranges allows to increase the efficiency of radar detection of the objects on a background of interferences from sea surface. Reflection characteristics of a sea in centimeter and millimeter wavelength range and restrictions related to their correlation property are the objects of researches and description in this paper. In this paper there are represented the results of experimental research of statistic characteristics (spectrums, distribution laws) of sea reflections including the case of their mutual processing as marks and outputs of narrowband Doppler filters. There are obtained the relations for estimation of working characteristics of the system complex in case of multiplexing and additive method of information aggregation. It is carried out comparison of the results with machinery experiment using real records of sea reflections. The basis is full-scale experiment together with mathematic modeling. It is shown that sea reflections correlation in centimeter and millimeter wavelength ranges is a factor restricting the efficiency of interconnecting of these ranges systems.
