摘 要: | In this paper,an improved design approach for the double dispersive SAW pulse compressionfilters is given.Based on the computer simulation of the filter performances,by modifying the weightedenvelopes of the filter finger lengths,the approximate design formulas have been obtained. Usingthese formulas,three sorts of samples of the pulse compression filters are designed and fabricated.The experimental results indicate that the sidelobe level have achieved up to-37dB in the best situation.
