Description: This paper contains principles for improving approach radar receiver that is the part of the ground controlled approach system РСП-10МН. The purpose of these principles is introduction and display coordinate information. Automatic tracking channel principles of plane constructing are present in this article. These principles using Doppler filtering, automatic tracking channel joint channel phasing and radar clutter compensation. It may be used improved precision approach radar at the final stage of landing.
Keywords: precision approach radar, difficult weather terms, automatic tracking channel, coherent integrator, moving target indication
