Some parameters are selected to evaluate the jammer’s effectiveness, which are suitable for TT&C systems. With the introduction to traditional blanket jamming and deception jamming, the effective blanket jamming as well as the emphasi s of study on deception jamming are pointed out as interfering with the TT&C systems based on DS/FH. This work of fers some references for the future work such as jamming and designing the TT&C systems based on DS/FH. Keywords: DS/FH; TT&C; Evaluation parameters; Blanket jamming; Deception jamming 1 引言 随着信息化电子干扰的发展和空间作战的提出,测控系统必须具有很强的抗干扰、抗截获能力。 DS/FH 混合扩频体制综合了直接序列扩频系统和跳频系统两方的优点,是目前国内外公认的最有生命力的抗干扰体制。采用该体制的测控系统在复杂的电磁环境中将具有很强的生存能力以及很高的可靠性。鉴于目前国内对于DS/FH 混合测控体制的研究只处于理论探索阶段[1,2] , 而有关该体制在干扰环境下
