%X A microwave polar interferometer using four-probe principle is presented, in which four-probe system is replaced by two T-junction waveguides in series with a tunable phase shifter between them. The interferometer is specially suitable for measuring the parameters of plasma transient process, and has the capability of displaying transmission, reflection, and polar characteristic with the origin of its coordinates at the same time.The experimental photographs of a transient plasma in the daylight lamp are clear at frequencies of 10 GHz and 35GHz.
