Specifically, receiving device is placed in receiving area, if the signal that transmitting terminal 1 issues is due in the transmission by object
Body blocks, and signal can only be by the end reflections on ellipsoidal reflector 2 close to receiving end, by the incoming reception of signal after reflection
When end, in order to meet in this case, receiving device can still receive signal, then need to connect determines according to actual conditions
The half power lobe width of receiving unit, and according to the diameter of the size of receiving device setting shielding surface 4, it is assumed that in receiving device
Full-size size is diameter, the circular flat that the second focus is the center of circle, and the signal issued by transmitting terminal 1 can not be put down across this
Face, the signal that transmitting terminal 1 issues can only be transmitted to 2 inner surface of ellipsoidal reflector along circular flat edge, and pass through ellipsoid
Second focus is reached after the reflection of 2 inner surface of reflector, in the letter for reaching the second focus after the reflection of ellipsoidal reflector 2
In number, by being compared to each other signal power size, wherein signal power is worth maximum signal for selection, and by the reflection point of this signal
It is denoted as θ to the angle between the line and horizontal line of second focus, if the angle of θ is less than or equal to antenna of receiving device
The half of half power lobe width, then this signal can be received equipment reception；If the angle of θ is greater than the half-power of receiving device
The half of lobe width then needs to readjust the size of ellipsoidal reflector 2, meets the angle of θ and is less than or equal to reception
The requirement of the half of the half power lobe width of device antenna.By skilled person will appreciate that, the transmission day of transmitting terminal 1
There are many lines, such as cylindrical antenna, butterfly antenna etc., and by taking cylindrical antenna as an example, cylindrical antenna is arranged in transmitting terminal 1, cylindricality
Signal power on antenna in intermediate region is most strong, then can choose several signaling points within the scope of this, which signaling point calculated
Power it is maximum, to determine θ.Other type antennas can also estimate the maximum several points of its signal power, and by calculating and comparing
