Ability analysis of radar fire control system against active jamming;

Applied the PID controlling strategy,after setted the PID controller rational parameters,which have strongly the anti-jamming ability.

Based on the primary measurement formula of radar anti-jamming ability for active masking jamming,the main factors connected with radar inherent anti-jamming ability for active masking jamming are discussed first,then radar additive anti-jamming ability for active masking jamming after using some kinds of anti-jamming measures is analyzed with simulations.

Aimming at the problem of wide interval Frequency Hopping Processing Gain arithmetic in the common used,adopt modificatory arithmetic and calculate wide interval Frequency Hopping Processing Gain,analyse BER and anti-jamming ability at the same time,point out superiority and shortage compared with traditional Frequency Hopping.

Influence of communication system s anti-interference capability on commanding efficiency;

The results of the test for 3 months show that the anti-interference capability of this type of extensometer has been impoved much more then those in common use.

A coordinated design of multi-factors method based on catch probability was put forward to improve anti-interference capability of missiles,according to analysis of the characteristics of OTH anti-ship missiles and the causes of catch probability,which was statistically computed thru uniform design.
