A new quadratic time-frequency distribution (TFD) with a compound kernel is proposed and a comparative study of several popular quadratic TFD is carried out. It is shown that the new TFD with compound kernel has stronger ability than the exponential distribution(ED) and the cone-shaped kernel distribution(CKD) in reducing cross terms, meanwhile almost not decreasing the time-frequency resolution of ED or CKD.
