Velychko D. A retransmission method of technical diagnostic precise radio engineering systems operation

In the thesis the new, retransmission method of precise radio engineering systems operation is proposed. This method is intended for systems operation in such condi- tions, when the main contribution to measurement errors is made by intensive interfering reflections from foreign ob- jects. The mathematical model of the proposed system is created. The new method made it possible to suppress on tens dB clutter reflections from the area, outside the main lobe of antennas directional patterns. Relations, determin- ing received signal at new method application, were ob- tained; the methods for signal information parameters se- lection and decreasing the errors, caused by spectrum para- sites components, were developed. A clutter reflections suppression was experementally investigated, different meters block diagrams were proposed and these meters parameters were estimated.
