Described the procedure for the synthesis filtering algorithms in a two-stage passive guidance system. Estimating coordinates of feature multiposition state in radar systems is the lack of simultaneity of arrival measurements from each of the targets at various positions, which leads to the receipt of non-simultaneity of the measurement to the overall filtering algorithm. This feature prevents the use of traditional filtering algorithms. To solve this problem in an article on the development of a two-stage filtering algorithm in passive guidance system, used contemporary mathematical analog to discrete linear filtering, making it possible to automatically take into account the non-simultaneity of arrival measurements from different positions. The main advantage of this algorithm and honors from the canonical algorithm is that the extrapolation is carried out with a small step closer to its accuracy analog algorithms, while the results of the measurements come from the much greater time interval to allow for non-simultaneity of arrival measurements from different positions.
