Potential range estimation accuracy in multistatic radar system in the implementation procedures of cooperative information processing

Improvement scheduling of performance data of air objects poses new challenges to finding ways to improve the processing algorithms trajectory information radar systems for the minimum allowable time interval. This is because the results of the trajectory measurements are used to assess the origin and purposes of the motion parameters, determine the degree of danger of aircraft and to address a number of specific tasks.

One way to improve the accuracy of the ranging parameters is the use of the procedures of the cooperative processing of coordinate measuring information in multistatic radar systems.

The aim of the article is to determine the potential accuracy coordinate measuring a multistatic radar system according to the number and type of positions ranging measurements.

The article considers the option of joint processing of range measurements, sums and differences of distances and derive expressions that can be considered a potential range accuracy depending on the number of positions and types of long-range dimensional mea-surement radar system implements cooperative processing of measurement information.

It is shown that, for the three-position radar system standard error of measurement of rectangular coordinates decreases 1,9−2,6 times depending on the type of measurement.

The use of redundant measurements for cooperative processing allows to achieve high accuracy in minimum time.
