Description
Technical field
The present invention relates to a kind of data editing methods of moon sight GPR Detection Data, in conjunction with telemetry for realizing moon sight
The data edition of GPR Detection Data works.
Background technique
No. three satellites of the goddess in the moon are succeeded in sending up on December 2nd, 2013 in Xichang Launching Site, landing on December 14 moon
Ball Mare Imbrium northern territory, rover lunar rover are successfully separated with lander, respectively carry out detection operations.Moon sight radar is as the goddess in the moon
The upper important scientific load of No. three " Jade Hare number " lunar rovers, during lunar surface detection, the effective mileage detected in total is greater than
100m。
Moon sight radar is divided into three phases in the work of lunar surface, and the first stage is the detection work in the time in first month daytime
Make, lunar rover advances to navigation spots N0108 point from navigation spots N0101, which is mainly the Orbital detection stage, to moon sight radar
Several important parameters in two channels for example when window, accumulative frequency, the repetition rate of impulse ejection, receiver signal gain mode and
Decaying setting, is tested, and has finally been determined that radar works the parameter of preferable state.Second stage is the time in second month daytime
Interior detection operations, lunar rover advance to navigation spots N209 point from navigation spots N0201, and the stage radar groundwork is fixed one
Parameter under be unfolded detection.Three phases are third month daytime and later working stage, and moon sight radar is in navigation spots N0209
The fixed point of expansion detects.One channel central frequency of moon sight radar is 60MHz, and corresponding bandwidth is 40MHz-80MHz, moon sight radar two
Channel central frequency is 500MHz, and corresponding bandwidth is 250MHz-750MHz.
There are following features in the work of lunar surface for moon sight radar: first, detection of the lunar rover on lunar surface is not to connect
Continuous, it loiters, there is a large amount of fixed point repeated data；Second, there is also differences for the speed that different zones are advanced, and will lead to
There is a problem of that scale is inconsistent after radar data is spliced；Third, every time when booting, due to space environment and Rover attitude
Difference, data starting sample point can have differences, and can have the phenomenon that misalignment after data splicing；4th, road in radar data
The location information of head is very little, about updates per minute, can no matter when Primary Stage Data screening or later data processing summarize
It is not high with property.For subsequent better interpretation moon sight GPR Detection Data, need combine telemetry to original radar data into
Row data edition.
Existing data edition work mostly uses subjective data edit methods at present, by manually checking radar data, leads to
Cross data characteristic original GPR Detection Data is deleted, the operation such as polishing, lack effective reference frame.These methods
Disadvantage is do not have accuracy, referential, and common processing result solves more.It is desirable to have a kind of effective moon sight thunder
Up to the data editing method of detection data.
