This method is compared with classical noise jamming technique by means of SJR (Signal to jamming Ratio) gain and jamming power gain of SAR system.
讨论了这种干扰方法对合成孔径雷达图像的干扰效果。
Vortex flowmeter is a widely used hydro-vibration flowmeter. Its poor noise to signal ratio and anti-jamming ability, however, limit its application.
涡街流量计测量应用广泛，但小流量信噪比低、抗干扰性能差。
