Airborne side-looking radar area coverage detection route planning method

Abstract

The invention relates to a side-looking air-borne radar (SLAR) area-covering detection route planning method and belongs to the technical field of route planning. The method achieves route planning on the basis of a method of performing circular framing to a sea surface area or a ground surface area awaiting detection. The method is simple and is especially suitable for areas which are approximately circular or have many branches and are diffused uniformly. In a waypoint calculation method of detecting a rectangular detoured route by means of SLAR area-covering detection, according to the characters of a detection blind zone of side-looking radar, a detoured route is employed to achieve the area-covering detection; and furthermore, with consideration of efficiency and availability of the route algorithm, the rectangular detoured route having fixed one-way route length and route spacing is employed. On the basis of detection mechanism, installation parameters and performance parameters of the side-looking radar, with detection coverage of the circular framed zone as a target, a reasonable route initial point, entrance direction, terminal, one-way route length and route spacing are calculated, thus ensuring the area-covering detection mission is accomplished.

Description

technical field [0001] The invention relates to the technical field of route planning, in particular to a route planning method for area coverage detection of an airborne side-looking radar. Background technique [0002] The airborne side-looking radar has all the inherent functions of other radars, can work day and night, and can detect targets except in severe weather conditions, especially the unique ability of large-area imaging makes it often used in tasks such as ocean monitoring, regional patrol and topographic mapping middle. [0003] For the side-looking radar installed on both sides of the aircraft, the area it can detect is two belt-shaped areas roughly parallel to the flight path, and there is a detection blind area under the belly of the aircraft. When performing detection missions in specific areas, route planning is usually carried out before takeoff, and the carrier aircraft can conduct coverage detection of the area along the planned route. For areas with ...

Problems solved by technology

For areas with detection value found or temporarily assigned during the flight, the pilot can only temporarily estimate the route based on experience. There are two problems in this method: on the one hand, the estimated route will distract the pilot's attention and increase the operational burden. It is not conducive to safe flight and mission execution; on the other hand, the manually estimated route cannot guarantee the coverage of area detection
