Embodiment
As shown in Figure 1, the present invention is by analyzing the wireless WiFi signal utilizing directional antenna to receive, in conjunction with the intrinsic parameter of directional antenna, horizontal radiation receiving angle and vertical radiation receiving angle, judge the orientation in wireless WiFi signal source, provide the concrete physical message of plane radio WiFi signal orientation radar map and the signal list received and each signal.Directional antenna receives wireless WiFi signal, (orientation angles information is exactly the intrinsic parameter of directional antenna to provide general orientation angles information with its intrinsic physical parameter (horizontal radiation receiving angle and vertical radiation receiving angle), such as, the horizontal radiation receiving angle of directional antenna is 10 °, so, resolution is exactly 10 °); According to the angle that intrinsic parameter and the directional antenna of the wireless WiFi signal received and directional antenna horizontally rotate, analyze the refined orientation judging wireless WiFi signal, and show with the form of orientation radar map.Every specifying information of wireless WiFi signal comprises signal name (SSID), signal intensity, MAC Address, cipher mode etc.
Specific implementation process of the present invention is as follows:
1) the level 360 ° rotation of directional antenna is controlled;
2) receive wireless WiFi signal and resolve;
3) specifying information (signal name, signal intensity, MAC Address etc.) of wireless WiFi signal is obtained;
4) by this information of signal intensity, the signal intensity profile data of certain wireless WiFi signal on level 360 ° of directions (corresponding angular resolution can think the horizontal radiation receiving angle of directional antenna substantially) are obtained;
5) according to weighted calculation process, the optimum judgment value of certain wireless WiFi signal orientation angles is in the horizontal direction drawn;
6) orientation angles of each the wireless WiFi signal finally obtained is depicted on radar map.
Method of the present invention can to taking directional antenna as the center of circle, and the orientation in the wireless WiFi signal source within the scope of radius 100 meters judges more accurately.
In practical operation, the implementation procedure of the inventive method is:
The first step: based on the control command of Palco-D agreement, controls the The Cloud Terrace that horizontally rotates of carrying directional antenna;
