| Abstract: | An analysis of frequency estimation of radar coherent pulses is made as well as the intermediate frequency sampling condition is investigated.On the basis of data collected from A/D collection system together with MATLAB,simulation is carried on.The arithmetic is modified when phase breakings happen.The feasibility of accurate frequency estimation method that adequately used the coherent property is verified,which is useful for the engineering. |
