Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] As shown in the figure, the present invention establishes a regional autonomous network based on Doppler active microwave radar sensors. exist figure 2 The microwave radar sensor nodes in the dotted circle area shown constitute the local area network LAN1. They monitor the effective area determined by the nodes in LAN1. Generally, the coverage area of ​​four nodes is 2.34 times of that of a single node. The sensor nodes in each group of LAN are only responsible for the central node where they are located, and transmit the collected information to LCN (Local center node). LCNs are a series of DSP (such as ADSPADSP-21xx) processors with strong floating-point budget capabilities, which can perform ICA analysis and bispectral feature extraction on data that has been simply preprocessed by the node. Neural network classification requires complex ...

Abstract

The invention discloses an intelligent anti-invasion microwave radar wireless sensor network, comprising an area autonomous network based on a Doppler microwave sensor. The invention applies independent element analysis arithmetic to complete multi-target separation via internal interactive information among the Doppler microwave sensor nodes in the same defence area network, and at least uses small wave neural network characteristic to judge the number and type of invasive bodies according to the separated signal. The invention sufficiently utilizes the information of the local defence area network held by the nodes to obtain the number of invasive bodies, which largely improves signal-noise ratio to realize intelligentization of the whole network and to fully reduce rates of false alarms and missed alarms.

Description

technical field [0001] The invention belongs to the related fields of distributed network computing, intelligent information processing, collaborative information processing, etc., and relates to a microwave radar wireless sensor network. . Background technique [0002] A wireless sensor network is a network composed of large-scale randomly arranged sensor nodes, etc., which aims to perceive the real physical space. Due to the uncertainty and dynamic characteristics of physical space signals and their states, how to cooperate with multiple sensor nodes and obtain correct information about the physical world from the uncertain, incomplete, partially incomplete or even wrong signals collected by them Information is an important subject of intelligent information processing. On the other hand, the wireless sensor network itself is also facing major challenges. The availability of network nodes in wireless sensor networks, the communication distance of nodes, the computing pow...
