Research on Radar Noise Figure Measurement Based on Synthetic Test

In order to reduce the measurement error of noise figure of radar receiver, this paper studies the method of gain measurement based on the synthetic test. By correlating the noise figure to the gain, it is proposed that the measurement precision of noise figure can be improved by employing the multiple sorts of measurement instruments attached to the equipment to do a cooperative measurement. And the feasibility analysis and experiments are performed on the receiver by using the gain measurement method. Experimental results show that this proposed method could measure effectively the noise figure of radar receiver, which provide a reference for the measurement of radar noise figure.
