Embodiment Construction
[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings. The three-dimensional three-dimensional radio signal direction-finding and positioning method of the present invention is to set the three-dimensional three-dimensional antenna array to receive the wave path difference signal, demodulate and process the received signal with phase difference, establish a full frequency band / spatial point sampling database model, and The data after real-time data processing is compared with the full frequency band / spatial point sampling database model, and the accurate orientation value is taken out and displayed on the three-dimensional coordinate system interface in five steps.
[0017] Wherein said setting three-dimensional antenna array, at first is to select a plurality of directional antenna vibrator with directional function, its bandwidth, gain, impedance and each parameter all consistent, it is respectively placed in the ...

The invention discloses a three-dimensional radio signal direction finding and positioning method which comprises the steps of setting a three-dimensional antenna array, carrying out demodulation and data processing on a wave path difference signal generated by the antenna array, establishing a full frequency band / space point sampling database model, comparing the processed data and the full frequency band / space point sampling database model, and taking out an azimuth value and displaying the azimuth value. According to the method, the composite directional antenna oscillator and the special combination are used to receive an echo signal, according to the digital extraction of a wave path difference, a phase difference, and an angle difference generated by a signal by an antenna, through data processing and database model comparison, a precise azimuth value is restored and displayed. The method creates a 3D direction positioning, and a major breakthrough from a plane direction finding to three-dimensional positioning is realized. The existing complicated signal source search work is simplified, the working efficiency is improved significantly, and the defect of the prior art is made up. The method has the advantages of novel and unique conception, reasonable and scientific step design, accurate and reliable positioning data, and good popularization and application values.
Description
technical field [0001] The invention relates to a direction-finding and positioning method in the radio application field, in particular to a stereo direction-finding direct positioning method for searching a radio signal emission source. Background technique [0002] Those skilled in the radio application field know that the existing radio direction finding technology can only complete the azimuth angle indication of the incoming signal wave in the horizontal direction, and the real pointing point of the signal source is on the extension line of the horizontal azimuth indication angle. For the wide-area space of the pitch angle perpendicular to the horizontal azimuth, there will be a direction finding blank. That is to say, signals above the water level and high floors cannot be measured by the direction finding system of fixed monitoring stations or mobile monitoring stations, and can only be searched manually. In reality, to search for the source of signal emission in a ...
