Abstract： SAR has multiple working modes. When there is a varying degree of demand for parameters such as surveying bandwidth and resolution，different working modes are adopted by controlling the direction and timing of beam irradiation.Diffrent interference methods are required for different working modes of SAR to achieve the most appropriate interference with the least amount of resources.Among them，flexible noise interference based on two-dimensional position shift modulation with controllable noise band position area size is adopted for strip mode and scanning mode；a confusion interference method based on active cancellation is proposed for the bunching mode and sliding bunching mode，which uses the weak points of active cancellation interference and false target interfer ence to confuse the real target area and the interference target area.

Key words：synthetic aperture radar;electronic countermeasure；active cancellation
