摘要：<p>PURPOSE:To perform continuous tracking, to stably and accurately guide a mother machine to a radio radiation source, and to accurately and speedily discriminate the number of times of pulse repetition by providing a receiver with a target memory and a pulse analyzer. CONSTITUTION:The reception frequency of an antenna 1 is discriminated 11 and a tracking guidance controller 9 controls the reception frequency of the receiver 2 according to the discriminated frequency. The sum signal and difference signal from the receiver 2 are A/D-converted 4 and the amplitude, pulse arrival time, pulse width, and angle error are detected 12, 13, 14 and 7. Respective data on the amplitude and pulse arrival time are written in the target memory 16 and then utilized as tracking and guidance information. An address generator 15 uses reception frequency data and angle control data indicated by the receiver 2 and an antenna servo 3 from the controller 9, angle error data from the detector 7, and pulse width data from the detector 14 as addresses of the memory 16. The analyzer 17 compares the pulse repetition time in a tracking data memory 10 with the pulse arrival time in the memory 16 to accurately and speedily discriminate the number of times of arrival pulse repetition.</p>
