Description

Technical Field

[0001] This utility model relates to the field of direction finding technology, specifically to a miniaturized radio direction finding instrument. Background Technology

[0002] A radio direction finder is a device used to determine the direction of a radio signal source. It is widely used in navigation, search and rescue, and amateur radio. By receiving radio signals and determining the direction of the signal source, it helps track the location of moving signal sources and identify and locate sources of radio interference. Its working principle involves using a directional antenna to receive radio signals, processing the signal strength or phase difference to determine the signal direction, and displaying the signal direction on the device, usually in degrees.

[0003] A radio direction finder typically consists of an antenna system, receiver, signal processing unit, display unit, control unit, power supply unit, and connectors. These components work together to ensure the device can accurately determine the direction of radio signals. However, existing radio direction finders use various connection methods to interconnect the components, including coaxial cables, external cables, and power lines. The types and quantities of cables are numerous. Effective management of the cable bundles requires a dedicated cable compartment. For example, the utility model patent application CN202421869907.7, entitled "A Radio Direction Finder," uses a cable compartment for centralized management of the cable bundles. However, this method also increases the size of the radio direction finder. With technological advancements, the application of radio direction finders in fields such as aircraft and ships is increasingly trending towards miniaturization. Therefore, there is an urgent need for a miniaturized radio direction finder to solve the aforementioned problems. Utility Model Content
