Description

technical field [0001] The invention relates to a monitoring and direction-finding system based on an aircraft-launched interferometer. Background technique [0002] With the widespread use of wireless electromagnetic waves in production and life, radio direction finding technology has also developed. Radio direction finding is based on the propagation characteristics of electromagnetic waves, using instruments and equipment to measure the direction of incoming waves of radio waves; It refers to the direction that the radio wave reaches in the real electromagnetic environment where the direction finder is located. The ultimate purpose of radio direction finding is usually to determine the "direction of the radiation source" and "the specific position of the radiation source". [0003] However, the current radio direction finding technology generally still stays in the ground equipment for direction finding. Due to terrain reasons, the effect is poor and the accuracy is low. ...
