Embodiment Construction

[0015] In order to reduce the influence of the mast on radar shading, the two navigation radars are arranged in a V shape, so that when the two radars are used at the same time, they complement each other, effectively improving the detection capability of law enforcement. The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Taking a marine police ship as an example, the maximum size of the outdoor unit of the X-band navigation radar including the antenna is: 2700*364*506mm (length*width*height), and the height of the antenna is 140mm. The maximum size of the S-band navigation radar outdoor unit is 3662*650*750mm, of which the antenna height is 340mm. This type of ship requires two radar V-shaped arrangements, such as figure 1 As shown, considering the radius of rotation of the two radars, L2≥2700 / 2+3662 / 2, L3≥2700 / 2, L4≥3662 / 2 during the arrangement, and the length of the common blind zone L1 formed shou...

Abstract

The invention discloses a ship navigation radar visual field complementary optimizing method. The method comprises the following steps: arranging two navigation radars on a ship mast by mainly using V-type layout, configuring the navigation radars in an X wave band and an S wave band, and installing the two radars in parallel, realizing blind area mutual compensation shielded by the mast through the X wave band / S wave band navigation radars; and through staggered layer layout in a vertical direction, simultaneously considering the mutual shielding effect between the two navigation radars, andrealizing no mutual interference problem within a main lobe wave beam range of the two navigation radars. The optimizing method is capable of realizing a maximum visual field while the two navigationradars are simultaneously normally operated, no overlapping, wherein a non-blind area in 360 degrees can be achieved while the two navigation radars are simultaneously operated.

Description

technical field [0001] The invention relates to the detection capability of ship navigation radars, in particular to a method for complementary optimization of horizons of ship navigation radars, in particular to a method for complementary optimization of horizons of two navigation radars installed on the same mast. Background technique [0002] With the development of electronic technology, the functions of navigation radar are becoming more and more perfect, and the degree of automation is getting higher and higher, which makes navigation radar play an important role in navigation. Generally, ships are equipped with two navigation radars of X-band and S-band, which are used to detect and identify targets such as ships on the sea, land and islands. [0003] The conventional navigation radar is arranged on the top of the ship's mast and on the centerline of the ship, and the two radars are arranged in a staggered layer one above the other. inconvenient. Considering the lim...
