Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many of the details listed in the specification are only for readers to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.

[0029] When the radar detects the ship target, in addition to receiving the scattered wave of the ship and the scattered wave of the sea level, it also receives the scattered wave formed by the coupling between the ship and the sea level; among them, the dihedral angle formed by the side of the ship and the sea level is important Scattering source. The sea level target scattering model is as follows figure 1 shown. figure 1 (a) represents the reflection of the ...

Abstract

The invention discloses a ship stealth apparatus and method. The apparatus comprises a curved plate, a first fixing device and a second fixing device. The curved plate that is fixedly arranged at an external surface of a ship side board and protrudes outwardly is used for reducing radar wave scattering. The first fixing device connected with the upper end of the curved plate is used for fixing the curved plate above the ship. The second fixing device connected with the lower end of the curved plate is used for fixing the curved plate below the ship. With the apparatus and method, a strong scattering structure formed by the ship side board and the sea level can be changed, the characteristic signal of the ship can be reduced, and the good stealth effect can be realized, thereby effectively reducing the probability that the ship is found by an enemy radar and is hit by the weapon of the enemy and improving the survival capability, defense penetration capability, and fighting capability of the ship.

Description

technical field [0001] The invention relates to the field of signal feature control, in particular to a ship stealth device and method. Background technique [0002] The sea combat ship is a mobile combat platform at sea. It has both offensive and defensive capabilities, and has a powerful strike force. It plays an incomparable role in modern warfare. However, ships on the surface of the sea are easily detected by radar and are attacked by air, sea and underwater. Ships with better stealth performance can greatly reduce the probability of being detected by radar and the probability of being hit by enemy weapons. [0003] At present, ship radar stealth mainly includes: appearance stealth, radar absorbing material and implementation of electronic countermeasures. Among them, the shape stealth refers to reducing the radar cross section (Radar Cross Section, RCS) by designing the shape of the ship, which is the main measure of radar stealth; Radar wave-absorbing materials are...
