Abstract

A radar or sonar guide homing system for aircraft, ships, etc., makes periodic distance measurements between a stationary transponder location (56) and a mobile interrogator location (50). An "on course" signal (90) is given when the difference DELTA R between successive measurement readings is maximized, in a negative direction (i.e., the gap between the stationary and mobile locations is closing). Otherwise an "off-course" signal (86) is given. An "S-turn" manoeuvre confirms the accuracy of the readings. <IMAGE>
