Analysis of Tracking Performance about DS/FH TT&C Based on Ambiguity Function

After introducing the ambiguity function theory of radar analysis, wideband ambiguity function about Direct Spread/Frequency Hopping (DS/FH) signal is derived out in this paper. From the point of signal simulation ambiguity figure, the tracking performance is studied and analyzed, that includes ambiguity character and signal resolution under the influence of frequency switching time and phase discontinuous. Conclusion shows the following design difficulty based on feasibility in DS/FH TT&C.
