Set may than report interference source position is farther or the position in actual interference source is likely located to fly to and reports the way of interference source
In, and there is also differences for the height in actual interference source and the height of report interference source.
S3: when monitoring that radio signal strength reaches a scheduled threshold value, direction finding is carried out to targeted radio and is determined
Position, and fly in the position that the corresponding position of the threshold value begins around report interference source.
The scheduled threshold value can select a moderate threshold value according to the Strength Changes of the signal monitored in the air)；Example
Such as: 20dB, 50dB.
When aerial platform reaches the position of the threshold value, start to be diversion around report interference source.In some implementations
In example, the center of circle being diversion is taken on the straight line of course line, the position near report interference source, at this time can be with the threshold value
Round tangent line is done in position, is that 500 meters, 1000 meters, 2000 meters or larger radius are diversion with radius, as shown in Figure 5；It is preferred that
Ground, the center of circle being diversion take in the position of report interference source.
In different embodiments, the position flight around report interference source can also use other tracks, such as just
Shape, triangular form or flight etc. of turning back.It is that finding other radio signal strengths is scheduled threshold value around the purpose of flight
Point, any available radio signal strength of the flight path used is the flight path of the point of scheduled threshold value.
S4: in the flight course, then when finding identical with the predetermined threshold position of at least one monitoring signals intensity,
Direction finding and positioning are carried out to targeted radio, and recorded.
When finding identical with the predetermined threshold position of two monitoring signals intensity, similarly targeted radio is surveyed
To and positioning, therefore the intersection point of the straight line in the targeted radio direction obtained according to the direction finding of two points be possible target without
The position of line electricity.
When finding identical with the predetermined threshold position of more than two monitoring signals intensity, similarly to targeted radio into
The probability firmware to Target Wireless electric position may be implemented according to the direction finding of multiple spot in row direction finding and positioning.
S5: cross bearing and probable ellipse are carried out according to the signal strength of the monitoring point of determining at least two, direction finding result
Statistics, and provide the maximum location point of possibility.
When finding identical with the predetermined threshold position of a monitoring signals intensity, according to the result and predetermined threshold of record
The direction finding of corresponding first point record and location data can be realized and be positioned to targeted radio.
When finding identical with the predetermined threshold position of multiple monitoring signals intensity, according to the signal strength of multiple points, survey
Cross bearing and probable ellipse statistics, the available maximum location point of possibility are carried out to result.
Using the flying method, can the fast and accurate monitoring for carrying out on-air radio electricity, greatly improve on-air radio
The efficiency and result of pyroelectric monitor.
For the purposes, technical schemes and advantages of the disclosure are more clearly understood, below in conjunction with specific embodiment, and reference
The disclosure is further described in attached drawing.
