Direction-finding system of lift-off interferometer

Abstract

The invention discloses a direction-finding system of a lift-off interferometer, which comprises direction-finding equipment and hitching equipment used for hitching the direction-finding equipment onto an aircraft. The direction-finding equipment comprises an electronic compass, a direction-finding antenna, a receiver, an X86 processing board, a WiFi module, a WiFi omnidirectional antenna, a GPS module and a GPS antenna. The output end of the GPS antenna is connected with the GPS module. The output end of the GPS module and the output end of the electronic compass are respectively connected with the X86 processing board. The output end of the direction-finding antenna is connected with the receiver. The receiver is connected with the X86 processing board. The X86 processing board is connected with the WiFi module. The WiFi module is in wireless communication with a direction-finding and monitoring terminal on the ground via the WiFi omnidirectional antenna. By means of the direction-finding system of the lift-off interferometer, the positioning function of a GPS and the navigation positioning function of an electronic compass are realized at the same time, so that the complete data collecting, receiving and processing process can be realized. Meanwhile, processed data are transmitted to the direction-finding and monitoring terminal on the ground in the wireless communication manner. Therefore, the real-time performance of the data transmission operation is ensured effectively.

Description

technical field [0001] The invention relates to a direction finding system of a lift-off interferometer. Background technique [0002] With the wide application of wireless electromagnetic waves in production and life, radio direction finding technology has also developed accordingly. Radio direction finding is the process of using instruments and equipment to measure the direction of incoming waves of radio waves based on the propagation characteristics of electromagnetic waves; determining the "direction of incoming waves" is a Refers to the direction that the radio wave reaches in the actual 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 location of the radiation source". [0003] If electromagnetic wave direction finding is carried out on the ground, due to terrain reasons, the effect is poor and the accuracy is low. The cu...

[0003] If electromagnetic wave direction finding is carried out on the ground, due to terrain reasons, the effect is poor and the accuracy is low. The current radio direction finding technology is developing towards air direction finding, that is, using aircraft to carry out direction finding;

[0004] However, at present, it is not yet perfect in terms of equipment installation and signal processing technology.
