Abstract


With the advances in weapons and its control technology GJ standard gradually reflect not suited at depth study on a more adapted to the system performance need new theories and their corresponding data processing method . This paper is a preliminary heuristic in this direction \An important task of the error data processing when shooting moving targets of anti-aircraft guns in the marching . First is based on to antiaircraft basic theory , summarizes the sources of error and antiaircraft firing hierarchical model , and through the analysis of the consistency of the random process , discussion of error correlation necessity ; followed by design a gross error in the screening data program improve the deficiencies in the past , this type of design . In this paper is : polynomial regression function , using the method of least squares approximation does not mean stationary random error , to replace the segment statistics mean traditional method ; to existing measured error sequence as a starting point , inspection of the error the normal distribution Relevance discussed random vibration characteristic of the actual system , the various random errors of the self - correlation and cross-correlation , and extraction of the autocorrelation function of the various error and generate respective error sequence shaping filter , to verify each error mean crossing time interval roughly geometric distribution ; cross-correlation coefficient for quantitative research orientation difference , the difference in height and body heading angle , pitch angle , roll angle between the degree of influence . The solution of these problems will be indicators for the error characteristics of the weapon system demonstration, design, testing , validation increase a correlation indicators .
