We theoretically and experimentally study the propagation properties of circular Airy beam (CAB) with a Gaussian envelope in Fourier space. The two parameters function can be used to control distribution spatial frequency, thus tune this modified CAB. When are chosen appropriately, size focal spot will reduced, maximum intensity especially abruptly autofocusing property greatly enhanced. Meanwhile, position remain almost same common experimental results show that proposed generated conveniently by using transform method as generate
