Abstract:
A Navy radar carries out a number of tasks. One of them is the acquisition of radar objects. Another task is a correction of cooperated object flight. One of the important tasks solved by the radar system is a task of receiving communication signal from cooperated object. In early offered structure of a NAVY radar with its having an adaptive space frequency time processing of signals the communication signal from cooperated object will be suppressed by adaptive algorithm. One of the reasons is a non maximum antenna directivity angular position of signal source. Another reason is high power of communication signal from object. The article offers corrected schematics of signal processing in radar with its having an adaptive space frequency time processing of signal. The method is based on that fact that in this signal processing schematics a correlation matrix always calculated and we can calculate angular position of signal source. Object angular coordinates are determined by finding the maxima is the relief bearing. Then this information will be used in adaptive algorithm and it will provide information signal receiving and processing.
