| Abstract: |
| In regard to the anti-jamming issue of space TT&C monopulse tracking system, the characteristics of the countermeasures are discussed in the aspects of signal form, mechanism of TT&C, features of antenna and kinematics of target, implementation of mission, and the arrangement of the tracking stations, through the analysis of the monopulse countermeasures techniques of radar system. The possible platforms of jammer are analyzed. The evaluation formula of jamming intensity and the constraint condition of effective jamming of TT&C monopulse are provided. The effect of cross-eye jamming, AGC jamming and delay-retransmit jamming on TT&C monopulse tracking are investigated. These research achievements constitute the elementary framework of TT&C monopulse system countermeasures. |
