CHAPTER 2. TACTICAL AIR NAVIGATION (TACAN). INTRODUCTION (2) use the bearing and distance from a specific beacon to fix his or her geographic location. Before we begin discussing TACAN, you need to recall the definition of the polar-coordinate system. TACAN PRINCIPLES. The polar-coordinate system is a geometric system used to locate points on a plane. In electronics, it is The distance measuring concept used in TACAN. usually used for plotting antenna directional patterns. equipment is an outgrowth of radar-ranging techniques. Radar-ranging determines distance by TACAN is a polar-coordinate type radio air- measuring the round-trip travel time of pulsed rf navigation system that provides an aircrew with energy. The return signal (echo) of the radiated distance information, from distance measuring energy depends on the natural reflection of the radio equipment (DME), and bearing (azimuth) waves.
