Abstract : The identification and classification of radar targets is facilitated by a newly developed technique based on measurements of the differential phase shift of the target scattering obtained at two harmonic phase-locked frequencies. These phase differences are independent of target range and relative motion. The differential phase shift between two harmonic frequencies has been measured for various types of targets. The experimental results indicate that the differential phase shift can be used as a parameter in the classification or identification of targets. (Author)
