Illustrated by taking table 4 and the result of table 5 that step S208 is obtained as an example, obtain each reference rings in multiple positions 0 degree of RF energy frequency compensation error amount, 180 degree RF energy frequency compensation error amount, 0 degree of up-link frequency at place are mended Repay after error amount and 180 degree up-link frequency compensation error amount, be utilized respectively above-mentioned compensation error amount and calculate each compensation mistake The average value of the standard deviation of difference, the maximum and minimum value of each compensation error amount, and each compensation error amount.

Calculated using the compensation error amount of table 4 and obtain result as shown in table 6：

Calculated using the compensation error amount of table 5 and obtain result as shown in table 7：

Utilize the corresponding standard deviation of 0 degree of up-link error amount, the 180 degree up-link error amount of all reference rings Corresponding standard deviation, the corresponding standard deviation of 0 degree of RF energy error amount and the corresponding mark of 180 degree RF energy error amount Quasi- deviation, calculates the root mean square for obtaining standard deviation.Specifically, utilizing 12 standard deviations shown in table 6 herein and table 7, meter Calculate the root mean square for obtaining standard deviation.The root mean square for calculating obtained standard deviation is a parameter for evaluating compensation effect, mark The root mean square of quasi- deviation is smaller, illustrates that the effect of compensation is better.

It is another parameter for evaluating compensation effect to calculate obtained average value, and average value is closer to 0 explanation compensation effect Fruit is better；

Step S209 is specifically included：

S209A, judge whether the compensation error amount of current reference ring meets the first predetermined condition；

Whether first predetermined condition refers to the root mean square of standard deviation in first interval, wherein, the setting of first interval It can be adjusted according to actual needs, the scope of first interval determines the degree of accuracy of calibration；

Compensation error amount according to each reference rings calculates the root mean square for obtaining standard deviation, criterion deviation Whether root mean square is in first interval；

If the root mean square of standard deviation in first interval, is not selected differently from the position of last time in the first preset range Put offset, to any reference rings in any direction on position offset be adjusted, by after adjustment position offset make For the new position offset of reference rings, return and perform step S206；

Wherein, the position offset of which reference rings is specifically adjusted, can according to actual needs be adjusted, once adjust It is whole to adjust the position offset of one or several reference rings, and can only adjust the position of reference rings in one direction Offset can also adjust the position offset of reference rings in a plurality of directions simultaneously；And the value of adjustment can be pre- first Determine arbitrarily to choose in scope.

When the root mean square of standard deviation increases compared to the root mean square for the standard deviation that last computation is obtained, then it is assumed that contraposition The adjustment of offset is put so that position offset is away from real position offset.

For example, setting the position offset selection range of Z axis as [2.5,7.5], the position of the Z-direction of reference rings is inclined Shifting amount initial value elects 5mm as.On this basis, the position skew of the position offset of adjustment reference rings X-direction and Y direction Amount.

It can specifically be adjusted using dichotomy, for example, devX1 span is [- 1 ,+1], then can be first when adjusting Value -1,0 ,+1 these three values, if it is determined that calculated when being 1 from position offset the obtained root mean square of standard deviation compared to The root mean square that obtained standard deviation is calculated when position offset is 0 and -1 is big, then it is assumed that remote when position offset value is 1 Real position offset.Then next time, when adjusting again, interval was reduced into [- 1,0], and between value -1 and 0 in Point -0.5.The obtained root mean square of standard deviation and range boundary -1 and 0 are calculated when further according to the position offset calculated being -0.5 The root mean square of the standard deviation of calculating is compared, and span is reduced again, until finding the square of minimum standard deviation Root.According to this dichotomy, value is traveled through in the span of position offset.

If reference rings are completed with the adjustment in X-axis and Y direction, the first predetermined condition is met still without finding Position offset, then reference rings position offset in the Z-axis direction is adjusted using dichotomy.

If the root mean square of standard deviation performs S209B in first interval；

S209B, judge whether the compensation error amount of current reference ring meets the second predetermined condition；

Second predetermined condition refers to the corresponding average value of the corresponding 0 degree of up-link error amount of all reference rings, 180 The corresponding average value of up-link error amount, the corresponding average value of 0 degree of RF energy error amount and 180 degree RF energy is spent to miss The corresponding average value of difference whether all in second interval, wherein, the setting of second interval can be adjusted according to actual needs Whole, the scope of second interval determines the degree of accuracy of calibration；Compensation error amount according to each reference rings, which is calculated, obtains each Whether the AME of individual reference rings, judge each AME in second interval；

If AME is selected differently from the ginseng of last time without all in second interval in the second preset range Examine the error amount of ring, the error amount of any reference rings be adjusted, using the error amount after adjustment as reference rings new mistake Difference, returns and performs step S206；

Wherein, the initial value of the error amount of reference rings calculates the error amount of obtained reference rings for execution step S205； The error amount of adjustment reference rings can be step value of the initial error value plus setting of reference rings, specific step in second interval Long value can be configured according to actual needs；Preferably, step value is set to 0.01dB；

Error amount adjustment for reference rings can be the error amount that adjusts any one or more reference rings, can also It is preferential alignment error average value not in the reference rings of second interval；If AME is performed all in second interval S209C；

S209C, judge whether the compensation error amount of current reference ring meets the 3rd predetermined condition；

3rd predetermined condition is used to judge whether judgement of the end to compensation effect, and the 3rd predetermined condition can be all Whether the maximum of the compensation error amount of reference rings and the minimum value of the compensation error amount of all reference rings are all in 3rd interval It is interior, wherein, the setting of 3rd interval can be adjusted according to actual needs, and the scope of 3rd interval determines the standard of calibration Exactness；Preferably, 3rd interval could be arranged to [- 0.5dB ,+0.5dB]；

Maximum in the maximum for the compensation error amount for searching all reference rings, the compensation for obtaining all reference rings is missed Minimum value in the maximum of difference, the minimum value for the compensation error amount for searching all reference rings, obtains the benefit of all reference rings The minimum value of error amount is repaid, the maximum and the compensation error amount of all reference rings of the compensation error amount of all reference rings is judged Minimum value whether all in 3rd interval；

If the maximum for compensating error amount and the minimum value for compensating error amount are no all in 3rd interval, ginseng is judged Whether the position offset for examining ring travels through value in the first preset range, and whether the error amount of reference rings travels through second and make a reservation for In the range of value；

Specifically, if the first preset range [- 1mm ,+1mm], step-length is 0.5mm, and initial position offset is 0mm, Then judge whether the position offset of reference rings has been traveled through in -1mm, -0.5mm, 0mm ,+1mm ,+0.5mm, the second preset range Traversal method it is identical；

If the value of position offset has traveled through the first preset range, and the value of error amount has traveled through the second predetermined model Enclose, then expand the first preset range, the first preset range after will be enlarged by is as the first new preset range, new first The position offset of adjustment reference rings in preset range, and it regard the position offset of the reference rings after adjustment as new position Offset, returns and performs step S206；

It is understood that when the value of position offset has traveled through the first preset range, and the value traversal of error amount During the second preset range, it can not only expand the first preset range, the second preset range can also be expanded, it is predetermined second In the range of adjust the error amounts of any reference rings, using the error amount of the reference rings after adjustment as reference rings new error amount；

If the value of position offset does not travel through the value of the first preset range or error amount, not travel through second pre- Determine scope, then continue executing with the position offset that any reference rings are adjusted in the first preset range, in the second preset range The step of adjusting the error amount of any reference rings, and it regard the position offset after adjustment as two in the reference ring group of setting Two in the position offset of individual reference rings, the reference ring group that the error amount of the reference rings after adjustment is obtained as calculating The error amount of reference rings；Return and perform step S206；

For example, the value of position offset does not travel through the first preset range, it is assumed that the first preset range for [- 1mm ,+ 1mm], step-length is 0.5mm, is+1mm without value if value is -1mm, -0.5mm, 0 mm to position offset ,+ 0.5mm, now continues in the interior adjustment position offset of the first preset range [- 1mm ,+1mm], that is, make it that position offset can be with Value is+1mm ,+0.5mm；The now value of error amount value still in the second preset range so that position offset for+ When 1mm ,+0.5mm, it can be combined respectively with all error amounts in the second preset range.

If compensating the maximum of error amount and the minimum value of compensation error amount all in 3rd interval, worked as using described The compensation error amount of preceding reference rings, calculates the corrected parameter of the current reference ring.If compensating maximum and the compensation of error amount The minimum value of error amount is all in 3rd interval, then it represents that ergodic condition terminates so that compensation error amount meets above-mentioned condition Position offset is the offset distance between reference rings geometric center and electrical centre；
