Design of time-frequency distributions (TFDS) that are robust to the impulse noise influence is considered. The robust TFDS based on the robust short-time Fourier transform (STFT) are proposed. An efficient procedure to evaluate the robust STFT is given. Robust TFDS based on the robust STFT have better energy concentration around the signal instantaneous frequency (IF) than the robust STFT itself. Also, these TFDS are more resistant to higher impulse noise than the robust TFDS obtained using the local autocorrelation function (LAF) based minimization problem.
