Description

Technical Field

[0001] This invention relates to the field of radio positioning, specifically to a civilian active echo radio positioning system and method. Background Technology

[0002] In today's era, with the development of the information age and the increasing variety and number of various means of transportation, the positioning of various objects has become a very important issue. Previous positioning tools are no longer sufficient to meet the needs of precise positioning. For example, between vehicles, between airplanes, and between ships, navigation accuracy needs to be improved.

[0003] Current positioning methods mainly include radar detection and GPS positioning. Radar detection involves emitting electromagnetic waves, which are reflected back by the object being detected. This requires extremely high power and weight, and is easily affected by weather. However, if the object being detected actively transmits the signal back after receiving the positioning request signal, instead of reflecting it back, the above disadvantages can be avoided. GPS positioning is limited by accuracy and weather conditions, and can mostly only be used as an auxiliary positioning tool.

[0004] Given the current severe challenges in positioning, it is essential to use a low-cost, high-precision positioning method that is less affected by weather conditions.

[0005] The existing positioning methods have the following problems: Radar positioning has excessive power, is too heavy, and is greatly affected by weather conditions, while GPS positioning is also greatly affected by weather conditions and has lower accuracy. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a civilian active echo-transmitting radio positioning system and method, which has the advantages of low power consumption, minimal weather-related influence, and high accuracy. It overcomes the problem of poor positioning accuracy in traditional positioning methods.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a civilian active echo-transmitting radio positioning system and method, comprising a self-antenna array, a self-signal processor and a self-power supply, and a counterpart antenna, a counterpart signal processor and a counterpart power supply. The self-antenna array transmits radio signals, which, upon detection, are actively transmitted back to the self-antenna. The system detects the differences in distance, phase, time frequency, or propagation time between each antenna in the self-antenna array and the counterpart antenna. These differences are then calculated by the self-signal processor using its own power supply, and by the counterpart signal processor using the counterpart power supply, to accurately determine the spatial relative positions of the self and counterpart.

[0008] Preferably, the self-antenna array detects the difference in distance, phase, signal frequency, or propagation time between each antenna in the self-antenna array and the radio signals transmitted by the other antenna to detect the direction parameters in the spatial location information.

[0009] Preferably, the positions of the self-owned antenna array, self-owned signal processor, self-owned power supply and the other party's antenna, other party's signal processor, and other party's power supply are interchanged, and the position information is fed back to the requesting party, in order to adapt to the installation difficulties of small size or large weight where it is not advisable for either party to place too many antennas.

[0010] Preferably, if both sides are equipped with their own antenna array, the other side's antenna, their own signal processor, their own power supply, the other side's signal processor, and the other side's power supply, then mutual positioning between the two sides can also be achieved.

[0011] Preferably, the number of each antenna in the self-contained antenna array is determined as needed.

[0012] Preferably, the number of antennas of the counterpart antenna is determined as needed.

[0013] Compared with the prior art, the present invention provides a civilian active echo radio positioning system and method, which has the following beneficial effects: Because it uses active echo transmission instead of reflected echo, the echo is larger than that of traditional radar reflected echo. Therefore, this method has the advantages of low power, high accuracy, low weight, and less susceptibility to weather conditions, which greatly promotes the convenience and high accuracy of positioning.

[0017] Please see Figure 1The six antenna arrays of our side transmit radio signals, which are received by the other side's antennas and then transmitted back.
