<p>PURPOSE:To display accurate measurement radar video by using a coordinate system for pseudo logarithm which can be also displayed by a raster scanning system. CONSTITUTION:An accurate measurement radar video 10 sent from an accurate radar device is sampled by a pulse train which will be a pseudo index function timely, so as to make it to be an X axis (distance axis), and it is written in frame memories 104 which are separated into high/low areas and bearing areas successively. A value of the pseudo index function can be freely set by an operator. The data of the frame memories in which the video of the high/low and bearing areas, that the X axis is indicated by the pseudo index function, is drawn are successively read out through a raster scanning system, thus allowing them to be displayed equivalently on a display screen by an accurate measurement radar video display system using a pseudo logarithm scale.</p> |
