The invention relates to a passive radar lightning-proof moisture-proof omnidirectional antenna which comprises a stand column and a cylindrical lantern ring connected to the stand column in a sleeving mode. A plurality of transverse rods are fixed to a circumferential surface of the lantern ring, an antenna is fixed to an end of each transverse rod, the lantern ring is installed on the stand column through an adjustable elastic assembly, and an installation height of the lantern ring on the stand column is adjustable. The elastic assembly comprises an adjusting column movably penetrating through a cylinder wall of the lantern ring, an elastic spring connected to the adjusting column in a sleeving mode, and a clamping block arranged at one end, located on an inner wall of the lantern ring,of the adjusting column. An accommodation cavity used for accommodating the elastic spring is arranged in the cylinder wall of the lantern ring, a baffle is arranged on a portion, located in the accommodation cavity, of the adjusting column, one end of the elastic spring abuts against the side wall of the accommodation cavity, and the other end of the elastic spring abuts against the baffle. A limiting cavity is arranged in a position, corresponding to the clamping block, of the inner side wall of the lantern ring, and multiple positioning cavities are arranged in an outer surface of the stand column along a longitudinal direction. The antenna is convenient to use, adjustable in antenna height and firm in installation relative to the stand column.
Description
technical field [0001] The invention belongs to the technical field of radar antenna technology, and in particular relates to a passive radar lightning-proof and moisture-proof omnidirectional antenna and a use method thereof. Background technique [0002] The radar antenna converts the spherical wave radiated by the feed into a plane wave through the reflector, so as to realize directional reception or emission of electromagnetic waves. There are various forms of radar antennas currently used. However, once these existing radar antennas are installed, their installation height cannot be adjusted effectively, and once the radar antenna is damaged, it is also inconvenient to replace. [0003] For example, a radar antenna in the prior art consists of a column and an antenna, wherein the antenna is fixed on the column by welding, so that the position of the antenna on the column is relatively fixed, and the antenna cannot be adjusted on the column according to the actual situat...
