The antiradar coatings of body surface are coated in, due to the influence of the factor such as weather, physical damnification, burn into be aging, its absorbing property can be gradually reduced, even recurrence is to the effect for inhaling ripple.And the antiradar coatings after coating cannot be removed（Remove and destroy）, so being that above-mentioned laboratory method cannot be applied to detect the reflectivity performance of the antiradar coatings being coated on object, can only be measured by special portable microwave absorbing coating reflectivity on-spot tester.But, on-spot tester employs probe and presses close to the mode that material is measured, its Electromagnetic Field principle and measurement result are different according to the Electromagnetic Field principle and measurement result of the metering system of defined in " GJB 2038-1994 radar absorbings reflectivity test method " from material model, both measurement results have certain correlation, but for material of different nature, its error has uncertainty.For example for the antiradar coatings of resonance, due to the problem of action principle（Mainly incidence wave direction is different）, the effect of resonance can not be embodied in the case where probe presses close to the mode of Materials Measurement, if the test result of the test result of on-spot tester and laboratory be compared, error is up to more than 10dB.For these reasons, the measurement result of on-spot tester can not check the performance of antiradar coatings according to conventional assessment mode.
It is within a long time to be coated on the antiradar coatings on weaponry surface to carry out long-term follow testing goal, periodically the microwave absorbing coating to weaponry surface is measured, judge its reflectivity performance with the increased decline degree of use time, maintenance, repair and replacing for microwave absorbing coating etc. provide clear and definite reference information, realize this purpose and need not compare with the measurement result in laboratory.
The content of the invention：
The method that the present invention provides one, the thinking for carrying out itself comparing analysis using the measurement result to the antiradar coatings at target same position realizes the assessment to material reflectance hydraulic performance decline situation.
A kind of method to the detection of microwave absorbing coating reflectivity performance long-term follow of the present invention, step is as follows：
In the equipment target that need to be detected, according to monitoring demand, several or tens feature mark poiXs are selected；
Spray painting sign is carried out to the feature mark poiX selected on the target surface；
In different time points, same feature mark poiX is measured：Determine initial reflectance data, and be stored in tester as comparison sample in the future；According to the time requirement of periodic maintenance, albedo measurement is periodically carried out again to all characteristic points using on-spot tester；Current measurement data is carried out into subtraction with initial sample data according to by Frequency point（DB values）Treatment, obtains the numerical value that antiradar coatings reflectivity declines；According to the specification that antiradar coatings are safeguarded, numerical value is declined to the antiradar coatings reflectivity at each feature mark poiX and is judged, provide maintenance scheme.
The method of the present invention carries out long-term follow detection using portable microwave absorbing coating on-spot tester to microwave absorbing coating reflectivity performance, solve prior art not enough, situ measurements based on portable microwave absorbing coating reflectance test instrument, realization carries out long-term follow and picks up survey to antiradar coatings reflectivity performance, is very suitable for equipping long term monitoring and the maintenance work of surface antiradar coatings reflectivity performance.
