N2 - To solve the problem of cross-range scaling of non-cooperative target ISAR imaging, a corresponding analysis method is proposed based on echo phase polynomial and intrinsic mode components, to inhibit the endpoint effect in the empirical mode decomposition process. Rotation parameters of the target are obtained through instantaneous frequency analysis and the aspect angle during the imaging period is calculated to get the cross-range resolution of the target. Based on the principle of ISAR imaging, the instantaneous Doppler expression of the echo is deduced and a kind of empirical mode decomposition endpoint estimation method is brought forward. Combined with the third order PPS estimation of change rate of the echo's instantaneous frequency, the simulation results confirm the feasibility of the algorithm.
