Abstract:

In order to solve the unprecedented issues during the TT&C system running，two fresh indicators named the stability of the hopping pattern and the stability of frequency hopping gain were presented. The indicators can improve the test system of TT&C. The novelty and importance in testing of TT&C were analyzed；the meaning of the indicators from both qualitative and quantitative aspects was defined；the test method of the indicators was provided，and a new algorithm used to correct the test error about the stability of the hopping pattern was proposed. At 1ast，a variety of visualization technologies were studied. The analysis and simulation results show that the indicators can describe the phenomenon effectively in the system，the methods can accurately complete the test and the visualization scheme can show the test results from different visions.

Key words: hybrid spreading spectrum TT＆C system, test method, stability
