Embodiment Construction

[0036] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0037] Such as figure 1 As shown, the array resource allocation method for the integration of opportunistic array radar tracking and communication disclosed in the present invention includes the following steps:

[0038] (1) Obtain the number M of tracking tasks and the number N of communication tasks undertaken by the current opportunity matrix, and assign One array unit is the tracking array resource, and the other array units are communication array resources, where Sum is the total number of array units in the opportunity array, and [·] is the rounding operator; that is, the array resources for tracking and communication are allocated according to the proportion of the number of tasks, and the tracking The communication array resources occupy M / (M+N) and N / (M+N) respectively.

[0039] (2) According to the number M of tracking tasks and t...

Abstract

The invention discloses an opportunistic array radar tracking communication integrated array resource allocation method comprising the following steps that 1, the tracking task number and the communication task number borne by the opportunistic array are acquired, and tracking and communication array resources are allocated according to the task number proportion; 2, multiple beams are generated by using the tracking array resources to track the target so as to construct a tracking effectiveness model; 3, multiple beams are generated by using the communication array resources to realize data link communication so as to construct a communication effectiveness model; and 4, the tracking effectiveness and the communication effectiveness are calculated by aiming at the current array resource allocation strategy, and the current resource allocation strategy is selected as the final allocation result if the tracking effectiveness and the communication effectiveness meet the preset thresholdrequirements; or the process returns to the step 1 and the array units are reallocated until the tracking effectiveness and the communication effectiveness meet the preset threshold requirements. According to the method, the opportunistic array resources can be reasonably allocated when the opportunistic array radar tracks multiple targets and communicates with multiple nodes so as to enhance theworking efficiency of the array resources.

Description

technical field [0001] The invention belongs to the field of radar resource management, and in particular relates to a method for allocating opportunistic array radar array resources with both tracking and communication functions in mind. Background technique [0002] The integration of radar communication systems can improve the availability and reliability of equipment, realize resource sharing and dynamic combinability, reduce system electromagnetic interference and energy consumption, and reduce maintenance costs, thereby improving the overall performance of electronic systems. As a special phased array antenna, the opportunity array antenna is based on a digital array, and a large number of antenna units and digital transceiver components are arranged arbitrarily in each open space of the platform. The opportunity of antenna allocation provides a solid guarantee for the design of radar communication integration, which is conducive to the organic combination and resource...
