Problems solved by technology

[0007] Both existing implementations require the detection node to transmit additional data information to the information fusion center through the report channel. Both of these two methods have the following problems: (1) Increase the complexity of the report channel design; (2) Significantly increase Large reporting channel data overhead, reducing the overall efficiency of the system
Especially for a reconnaissance network using a wireless reporting channel, the spectrum resource of the reporting channel is limited, so the above method is difficult to implement in a network using a wireless reporting channel

Embodiment Construction

[0020] Below in conjunction with accompanying drawing, the present invention is further described in detail:

[0021] In the reconnaissance network involved in the present invention, the cooperating N detection nodes maintain time synchronization, and use periodic detection to conduct uninterrupted reconnaissance activities, such as figure 2 shown.

[0022] A detection cycle is divided into three time slots: detection time slot, report time slot and information fusion time slot.

[0023] In the detection time slot, each detection node performs signal detection and gives its own local detection results l i (i=1,2,...,N). Among them, i is the detection node number, N is the number of detection nodes participating in the cooperation in the reconnaissance network, l i The value is

[0024]

[0025] In the report time slot, each detection node reports its own local detection results to the information fusion center through the report channel.

[0026] In the information fu...

Abstract

The invention discloses a method for estimating detection reliability in an intelligence survey network based on probability statistics. The method is used for an intelligence survey network which detects wireless signals with the cooperation of the multiple detecting nodes. The method uses local and global detection results stored in an information fusion center to estimate local detection result reliability of various detecting nodes such that the information fusion center is capable of considering the influence of the local detection result reliability on global detection reliability in information fusion. Compared with a method in the prior art, the method has technical advantages of (1) decreasing the design complexity of a report channel and (2) decreasing the data expense of the report channel and increasing system efficiency. As a result, the method is especially suitable for a survey network using a wireless report channel.

Description

technical field [0001] The invention relates to a method for estimating detection reliability in wireless signal detection by an intelligence reconnaissance network, in particular to a method for estimating detection reliability based on probability statistics. Background technique [0002] Radio signals are an important source of intelligence, and using electronic technology and equipment to detect and discover wireless signals in the air is one of the key technologies for intelligence reconnaissance. In intelligence reconnaissance, in order to improve the reliability of radio signal detection, multi-node cooperation is usually used to form a reconnaissance network with multiple detection nodes, and the local detection results of each detection node are fused through the information fusion center to give a global test results, such as figure 1 shown. Compared with the reconnaissance method of a single detection node, multi-node networking makes full use of the spatial div...
