technical field

The utility model relates to a personnel positioning system of an ultra-wideband through-the-wall radar, in particular to a personnel positioning system based on the remote comprehensive monitoring of the ultra-wideband through-the-wall radar.

Background technique

The research on UWB positioning technology abroad mainly includes: R.Jean-Marc Cramer et al. proposed a TOA estimation method based on the CLEAN algorithm; Joon-Yong Lee et al. proposed a generalized maximum likelihood estimation method; Pratt and Wheeler et al. proposed an ultra-wideband positioning method based on antenna arrays, which greatly improved the positioning accuracy of ultra-wideband positioning technology in non-line-of-sight environments compared with the previous method using a single antenna; Kegen et al. applied the Kalman filter algorithm In ultra-wideband positioning, target positioning and tracking are realized. The AetherWire company of the United States has developed the most advanced chip Aether5, which is based on UWB spectrum and CMOS development process. Its high integration makes its volume so small that it cannot be detected, its signal penetration ability is super strong, and its positioning accuracy can reach centimeter level. And the power consumption is extremely small. These advantages make it widely used in the world's military anti-terrorism. Ubisense, a British company, has also developed a UWB wireless positioning product, using TDOA/AOA joint positioning technology, working in the 5.8-7.2GHz frequency band, with a detection distance of up to 50 meters and a positioning accuracy of 15cm. The highly integrated UWB positioning chip developed by Aetherwire&Location is only the size of a coin, and has low power consumption and low cost. The positioning accuracy can reach centimeter level in an environment with less interference. Time domain company of the United States has developed a wall-penetrating perspective instrument based on UWB technology, which can penetrate several layers of walls to detect objects, and this product has also been widely used.

my country is still in its infancy in the research and application of ultra-wideband UWB positioning technology, but the country attaches great importance to the research in this advanced technology field, and encourages scientific research departments and related units to conduct research and theoretical innovation and invest considerable manpower, financial resources and material support. . In the national 863 plan, the communication technology uses the key technology in UWB wireless communication as the content of wireless communication commonality and innovative technology, and encourages the domestic communication industry to strengthen the research and development and investment of UWB technology; the project support of the National Natural Science Foundation of China also supports domestic UWB positioning technology Research has played a role in promoting and promoting. In addition, many universities and scientific research institutions have applied for projects in the research of UWB positioning technology, and have made certain progress and researched a number of theoretical results. Although there are a lot of theoretical research and related articles on UWB in China, the development of UWB system products has not yet seen mature products, and the application of UWB technology in personnel positioning systems is far behind the development level of British and American countries.

Existing personnel positioning methods include infrared rays, ultrasonic waves, radio frequency signals, etc., but none of them are suitable for indoor positioning through walls. Infrared rays are only suitable for short-distance transmission, and are easily interfered by fluorescent lamps or lights in the room, which has limitations in precise positioning; ultrasonic waves are greatly affected by multipath effects and non-line-of-sight propagation, and cannot be used in indoor environments; and radio frequency signals are common It is used in outdoor positioning system, but there are limitations in indoor positioning.

GPS is currently the most widely used outdoor positioning technology. It is a satellite navigation and positioning system developed by the United States for military purposes in the early 1970s. It mainly uses the measurement data of several satellites to calculate the location of mobile users, namely longitude, latitude and altitude. Typically used in vehicle navigation and handheld devices. On this basis, technologies such as enhanced GPS and assisted GPS have emerged, which can be widely used in fields such as aviation, navigation and field positioning. The advantage of using GPS for positioning is that the effective satellite coverage is large, and the positioning and navigation signals are free; the disadvantage is that the positioning signal reaches the ground weakly and cannot penetrate buildings, so it is not suitable for indoor positioning. In addition, the cost of the locator terminal is relatively high. The positioning accuracy that GPS can achieve is in the range of 5m-20m.

Currently popular Wi-Fi positioning is a positioning solution of IEEE802.11. At present, it is applied to small-scale indoor positioning, and the cost is low, but the Wi-Fi transceiver can only cover the geographical area within a radius of 90m, and is easily interfered by other signals, thereby affecting the positioning accuracy. It is not very reliable, and the positioning The power consumption of the device is high.

Bluetooth technology is used in positioning, and has many similarities with Wi-Fi. It is mainly used in small-scale positioning, such as single-story halls or warehouses; it also has the disadvantages of unstable positioning errors and large interference from noise signals.

It can be seen that with the development of positioning technology and the increasing demand for positioning services, wireless positioning technology must overcome the shortcomings of existing technologies and meet the following conditions: a) high anti-interference ability; b) high-precision positioning; c) Low production cost; d) low operating cost; e) high information security; f) low energy consumption and low transmission power; g) small transceiver volume.

The above several technical solutions cannot fully satisfy these requirements. UWB is used in wireless positioning, which can basically meet the above requirements, so it becomes the first choice for positioning through walls.
