The corresponding target measurement value of radar tracking error amount of section.When radar tracking error amount not in the normal range when, show radar
Abnormal tracking, these target measurement values cannot function as reference frame, therefore the target measurement value in this data segment is rejected.
Then according to the radar tracking error amount after rejecting to the front posture and vertical bar shape radar of horizontal stripe shape radar front
The front posture of front is adjusted.When being specifically adjusted, if between target azimuth measurement value and azimuth of target true value
Difference be greater than the first preset difference value, then setting angle of the horizontal stripe shape radar front on naval vessel is adjusted, so adjust
Horizontal stripe shape radar front posture；If it is default poor that the difference between target pitch angle measurement and target pitch angle true value is greater than second
Value, then be adjusted setting angle of the vertical bar shape radar front on naval vessel, and then adjusts vertical bar shape radar front posture.Its
In, setting angle and vertical bar shape radar front setting angle on naval vessel of the horizontal stripe shape radar front on naval vessel includes horizontal stripe
Installation position, pitch angle and levelness and vertical bar shape radar front installation side on naval vessel of the shape radar front on naval vessel
Position, pitch angle and levelness.Pass through setting angle, vertical bar shape radar front of the revised horizontal stripe shape radar front on naval vessel
The horizontal stripe shape radar battle array that ship gesture when scanning in the setting angle on naval vessel and each time is available when scanning each time
Front posture and front scan angle are carried out operation and are converted to revised target by face posture and vertical bar shape radar front posture
Measured value.Revised target measurement value is compared again with target true value, calculates revised radar tracking error
Value, to setting angle of the horizontal stripe shape radar front on naval vessel and to setting angle of the vertical bar shape radar front on naval vessel into
Row repeatedly adjustment, until the radar tracking error amount calculated is less than preset error value.

Judge whether radar tracking error amount is less than preset error value, if so, terminating, otherwise, calls adjustment module；
Module is adjusted, is used for according to radar tracking error amount, to the front posture and/or vertical bar shape radar of horizontal stripe shape radar front
The front posture of front is adjusted, and the target measurement value after front pose adjustment is calculated according to scan angle；
The data extraction module is also used to:
The scan angle and vertical bar shape of the corresponding horizontal stripe shape radar front of target measurement value are extracted from target tracking data file
The scan angle of radar front；
The error amount computing module, is specifically used for:
Each scan angle of each scan angle and the vertical bar shape radar front to match for horizontal stripe shape radar front, meter
The difference between corresponding target azimuth measurement value and azimuth of target true value is calculated, and calculates corresponding target pitch angle and surveys
Difference between magnitude and target pitch angle true value, as radar tracking error amount, horizontal stripe shape radar front and vertical bar shape radar
The corresponding radar tracking error amount of every a pair of scan angle of front forms radar tracking error value sets.
8. the error correction systems of two strips front phased-array radar as claimed in claim 7, which is characterized in that also wrap
It includes:
Data reject module, for be directed to radar tracking error value sets, be segmented according to corresponding scan angle, by radar with
Track error value sets are divided into multiple data segments, should if the radar tracking error amount in data segment is unsatisfactory for preset condition
The radar tracking error amount of data segment and its corresponding target measurement value are rejected.
