Abstract

PURPOSE:To enable observing of a target signal without any trouble, by preventing the occurrence of omission in writing into a frame memory of a radar video information produced due to asynchronism between a pulse signal, generated at each given degree of magnetic declination, and a rader transmission trigger signal. CONSTITUTION:Two digital angle signals theta and (theta+1), outputted from an angle signal generator 2, are fed to a signal feed control means 431. The signals theta and (theta+1) are stored in resistors 431 and 432, respectively, by means of a radar trigger signal. The signal of said signals is fed to an address generator 3 via a switching device 434, and a radar video information of an input buffer is written in a given X and Y address of a frame memory 6 according to an output signal of the generator 3. Then, after a radar transmission trigger is caused to delay (433), the signal (theta+1) is sent out to the generator 3. An information, being equal to a radar video information previously written in an address, is rewritten in the address of the memory 6 corresponding to the signal (theta+1). This permits preventing of the occurrence of conventional omission in writing.
