Besides amplitude, phase and Doppler frequency, polarimetric information is the fourth characteristic in the radar echo.
雷达回波信号中，除幅度、相位和多普勒频移外，还存在第四特征——极化信息。

The imposition of a curved phasecharacteristic reduces the peak amplitude of the waveform .
曲线形相位特性减小了波形振幅峰值。

The traditional method for amplitude-phase frequency characteristic calculation is first to solve the numerator polynomials and denominator polynomials of a transfer function.
