This paper establishes a model to distinguish three typical jamming scenarios faced by airborne fire con-trol radar,based on which the impact of amplitude and phase errors on the ability of airborne fire control radar to resist active jamming is analyzed.The simulation results show that amplitude and phase errors primarily affect the sidelobe clutter region,with little impact on the main lobe clutter region when the jamming signals enter through non-null point in sidelobe or through main lobe.In this case,the anti-jamming performance of the radar decreases with increasing amplitude and phase errors.In addition,when the jamming signals enter through sidelobe null,it causes the main lobe splitting,and the presence of amplitude and phase errors actually improves the anti-jamming performance of the radar.
