A novel method of measuring instantaneous frequency, azimuth and amplitude based on circle array is proposed. It is not limited by indeterminancy principle, and realizes truly instantaneous frequency azimuth and amplitude measurement. In this method, amplitude is estimated using the association between array elements received signals with reference signal; frequency and azimuth are estimated dexterously by FFT, because circle array is essentially periodic. Simulation results show that instantaneous frequency, azimuth and amplitude can be estimated accurately in very short time, and this method is effective
