Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific examples and with reference to the accompanying drawings.

[0029] The implementation process of the present invention is: the first step: each radar in the networking radar transmits a small amount of signals to identify the target features; and calculates the azimuth required for imaging each target according to the echo signals received by each radar To coherently accumulate time and observation dimensions; the second step: perform information fusion processing on the target according to the cognition results; the third step: under the premise of knowing the three-dimensional size information of the target, use the projection method to calculate the actual imaging effect of each radar on the target. The required observation dimension; the fourth step: select the radar according to ...

Abstract

The invention discloses an adaptive scheduling method for inverse synthetic aperture radar imaging resources in networking. On the basis of feature recognition on a target by each radar, three-dimensional information fusion is firstly carried out on the target; the time resource demand of the target in each radar is then analyzed; a radar for realizing target imaging is further determined according to constraint conditions for radar selection; and finally, a target imaging target resource scheduling model is established, the radar time resources are allocated reasonably, the resource scheduling for the imaging target is realized, and the working efficiency of the radar is improved.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to an adaptive scheduling method for inverse synthetic aperture radar imaging resources in networking. Background technique [0002] Judging from the current development trend in the field of radar technology, intelligence is the key direction for the development of radar technology in the future. Professor S. Haykin of the Cognitive System Laboratory of McMaster University in Canada first made a report entitled "Adaptive radar: evolution tocognitive radar" on the IEEE Phased ArraySystems and Technology Symposium in 2003, and proposed a phased array antenna technology-based, autonomous The concept of cognitive radar adapted to signal processing technology, and in 2006, in the paper "Cognitive radar: a way of the future", the concept of "cognitive radar" was systematically proposed and the basic block diagram of cognitive radar was given , and pointed out: "The develo...
