The Analysis of Electronic Countermeasures for SAL

The problem of ECM for synthetic aperture(imaging) Ladar(SAL,or SAIL) is studied in this paper.Although SAL is similar with SAR(synthetic aperture Radar),there are still some differences between them due to the different wave bands they used.So the methods of jamming for SAR are not always perfect for SAL.Special attention is carried out on these active jamming techniques for SAL,including noise barrage jamming,active deception jamming and scattering jamming.Several conclusions are obtained.A method of tracing-flight-scattering-jamming based on key target protection is presented.
