Abstract:
System features of automatic range tracking of space objects are studied by probing LFM signals. Stability boundaries and accuracy characteristics of automatic range tracking algorithms estimating motion parameters on the extra-atmospheric flight segment are evaluated. In each specific case besides traditional parameters our study allows determining sign and value of speed-error coefficient for range measurement by LFM signals. Under this condition steady operation and defined accuracy characteristics of automatic range tracking algorithms are ensured on the extra-atmospheric flight segment. The study results find relations between parameters of algorithms estimating motion parameters and speed-error coefficient to provide steady operation of space objects tracking by probing single LFM signals. The speed-error coefficient determines filter memory which defines a transition from sequence of probing signals to single LFM signals for probing space.
