Abstract : The patent describes an independent system to evaluate three dimensional radars which derive their height information from slant range and beam elevation. This transponder system consists of two major units, one of which senses the ship attitude and transmits this information to the control station. The second major unit on shore receives this information and uses it to update and preset conditions of the transponder, in accordance with the ship attitude, to synthesize a target at a given range, elevation and azimuth when the radar uses a specific beam to determine the angle of elevation of the target above the horizon.
