It is concluded that an offset feed parabolic antenna has the advantage in side lobe suppression over central feed parabolic antenna.
结论显示：偏角馈入抛物面天线较中心馈入抛物面天线在抑制远旁瓣方面有优势，在做低仰角扫描时不会产生远旁瓣回波；
Based on the principles that lateral offset-focus feed makes the antenna pattern deflect an angle, the multi-beam antenna can be used in passive imaging system.
