<p>PURPOSE:To know the trend of future deviation by operating estimated deviation after a predetermined time by an estimating operation part to display the same on a display part. CONSTITUTION:The position signal of an unmanned target airplane outputted from a radar antenna 2 and a position measuring system 3 is received by a deviation operation part 4. A target airplane position operation part 5 outputs the position signal as unmanned target coordinates data and a range/coordinates correction device 6 performs correction and unification so that the coordinates of a flight scheduled course and unmanned target coordinates data can be operated in the same unit system and a deviation operator 7 calculates the deviation in the horizontal and vertical directions of the target airplane to be outputted to a display part 9 and an estimating operator 10. The estimating operator 10 holds a plurality of deviation data in time series and takes the time lag thereof to calculate horizontal and vertical change rates and these change rates are multipled by a set time (t) to calculate estimated deviation after a time (t).</p> |
