Problems solved by technology
[0003] At present, most of the related products at home and abroad adopt fixed, vehicle-mounted, and hand-held designs. These erection methods have their own disadvantages: fixed erection is extremely inconvenient and dangerous, and cannot be moved. Become a blind spot, the handheld working frequency band is narrow, the sensitivity is low, the anti-interference ability is weak, and the time efficiency of direction finding is low
And it cannot meet the requirements of multiple direction finding systems such as interferometer, correlation interferometer, and spatial spectrum estimation at the same time

Embodiment Construction
[0016] The above and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings and embodiments.
[0017] Such as figure 1 A new type of portable five-antenna element direction-finding circular array is shown, including a circular array main body 1, a support arm 6, and a vibrator 7. The circular array main body 1 has high-end antenna elements 2 and low-end support arm mounting holes 3, and the upper part is centered on the central axis. Five non-detachable high-end antenna elements 2 are evenly installed on the axis, and an electronic compass (not shown) is installed in the upper cavity to provide accurate north-pointing functions. Five low-end support arms are evenly distributed around the central axis in the middle. One end of the hole 3 and the support arm 6 is connected with the main body 1 of the circular array, and two vibrators 7 are installed at the other end in the vertical direc...

The invention discloses a novel portable five-antenna-element direction-finding circular array and aims at providing a five-antenna-element direction-finding circular array which is small in volume, light in weight and capable of being disassembled rapidly and meeting demands of a plurality of kinds of direction-finding systems such as interferometers, correlation interferometers and space spectrum estimators and the like at the same time. The five-antenna-element direction-finding circular array includes a circular-array body, support arms and oscillators. The circular-array body is provided with high-end antenna elements and low-end support arm installation holes. The five non-removable high-end antenna elements are uniformly installed at an upper part, a center shaft being the axis. An electronic compass is installed in a cavity of the upper part. Five low-end support arm installation holes are uniformly distributed at a middle part, the center shaft being the axis. The low-end support arm installation holes are provided with double-screw bolts. One end of each support arm is provided with a threaded sleeve. The double-screw bolts are connected with the threaded sleeves. Two oscillators are installed in the vertical direction of the other end of each support arm so that the five low-end antenna elements are formed.
Description
technical field [0001] The invention relates to radio direction-finding equipment, in particular to a novel portable five-antenna-element direction-finding circular array. Background technique [0002] The direction-finding antenna array is an important part of the radio direction-finding equipment. The design method of the direction-finding antenna determines the erection method and the direction-finding mode of the direction-finding antenna, and also determines the performance indicators of the direction-finding equipment, such as operating frequency, sensitivity, and resistance. Interference, direction finding timeliness, etc. [0003] At present, most of the related products at home and abroad adopt fixed, vehicle-mounted, and hand-held designs. These erection methods have their own disadvantages: fixed erection is extremely inconvenient and dangerous, and cannot be moved. Become a blind area, the handheld working frequency band is narrow, the sensitivity is low, the an...
