Embodiment Construction

[0023] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0024] The technical scheme of the phased array radar timing design method integrated with the search and tracking of a kind of fixed tracking data rate of the present invention is as follows (the timing design method is as follows: figure 2 shown):

[0025] 1) Within a scheduling interval T, the scheduling interval T is evenly divided into N working beats according to the fixed tracking data rate, and the working beat is the minimum time unit of radar timing design. The search distance coverage area is divided into tasks of searching near areas and tasks of searching far areas. Allocate and execute the tracking and guidance task, the task of searching the near area and the task of searching the far area at the specified time within the scheduling interval T;

[0026] 2) Tracking and guidance task: assign a working cycle to perform the tracking and guidance ta...

Abstract

The invention relates to a timing design method for a search and tracking integrated phased array radar using a fixed tracking data rate. In a scheduling interval T, the scheduling interval T is equally divided into N beats according to the fixed tracking data rate so as to ensure that the phased array radar performs fixed data rate tasks such as target tracking and guidance while properly distributing the beats to search for a specified airspace, so the efficiency of searching is improved.

Description

technical field [0001] The invention belongs to the technical field of radar system design, in particular to a phased array radar time sequence design method that uses a fixed tracking data rate for task scheduling and integrates search and tracking. For the phased array radar timing design method that uses a fixed tracking data rate for task scheduling, the search and tracking integrated phased array radar timing design method realizes the timing compatible design of search, tracking, and guidance tasks, and ensures that the phased array radar performs tracking, guidance and other fixed data rate tasks. At the same time, resources can be allocated to search the specified airspace. Background technique [0002] Phased array radar technology has become the focus of radar technology research, because its phased array antenna can perform beam agility at the subtle level under the control of the computer, so that phased array radar can realize search, tracking and missile guidan...
