Number: 342/399
Name: Communications: directive radio wave systems and devices (e.g., radar, radio navigation) > Directive > Beacon or receiver > With transmisson of bearing or position determinative signals > Tacan
Description: Subject matter including a complete ultra-high-frequency polar coordinate (RHO-THETA) navigation system using pulse techniques, wherein the distance (RHO) function operates as distance measuring equipment (DME) and the bearing function is derived by rotating the ground transmitter antenna so as to obtain a rotating multiple pattern for coarse and fine bearing information.
