Abstract
For the frequency jittering radar, the problems of range migration and phase jittering among different pulses may occur during the long-time integration, which will affect the target energy integration. Therefore, a new coherent integration algorithm, namely, Frequency jittering based Radon-Fourier transform (FJ-RFT), is proposed. Based on jointly searching in the motion parameter space, the problems mentioned above can be simultaneously resolved and the coherent integration can be then realized. The Cramer-Rao lower bound (CRLB) and the Blind speed sidelobes (BSSL) of the proposed FJ-RFT are analyzed in detail. Finally, numerical experiments are provided to demonstrate the effectiveness of the proposed method.
