Abstract

PURPOSE:To establish the clear video display, which has a sufficiently wide azimuth direction on a display plane, by once storing a radar video and by reproducing the stored video at each timing of the same range over a preset radar sweeping period. CONSTITUTION:The transmission pulses of a transmission repeated pulse generator 15, which receives the output of a clock oscillator 16, are transmitted from an antenna 11. The reflected pulses are processed by a receiver 3, and a radar video is guided into a sample hold circuit 20 and sampled and held by the output of the oscillator 16. Thus, the memory is introduced through an A/D converter 21 into n number of series memory circuits 22 so that it is stored for the n sweeping periods. From the input signals to the circuits 22 and the output signals of the respective memories, the reproduced output is fed through an adding circuit 23 through a D/A converter 24 to a PPI indicator 17. On the other hand, the N mark pulses of an antenna angular detector 18 are delayed a preset quantity by a delay circuit 19 and fed to an indicator 17. As a result, it is possible to attain a clear image which is extended the n sweeping period in the azimuth direction in comparison with the actual image.
