In order to raise the tracing accuracy of a radar, the dynamic analysis must be taken for the design of radar antenna frame. In this paper, the connected loading dynamic substructural method is put forward for calculating its dynamic character. By means of the accurate dynamic condensatic method and bicoordinate conditions, we put the dynamic effect of slave substructures to a main substructure. An improved algorithm of nonlinear eigen problem[1] is used to calculate the lowest four eigenpairs of the antenna frame. For validating the theoretical analysis, the experimental research by ITD Method, Time Series Analysis Method and FFT spectrum analysis of the electrical pulse response are carried out, both results are fairly concordant.
