| Abstract: |
| Based on the analysis of active jamming mechanism and spread spectrum
Tracking Telemetry and Command (SS TT&C) signals processing principle, a method
using the ambiguity plots effective areas and the incision areas at a certain le
vel to evaluate inherent anti-jamming capability of SS TT&C signals is put forwa
rd. The smaller the computed areas become, the stronger the anti-jamming perform
ance gets. Simulation results show that the proposed metrics are effective to as
sess signals anti-jamming performance. The methodology is computable, which
provides reference for signals anti-jamming capability evaluation. |
