Example Embodiment
[0038] The frequency response compensation method of frequency agile signal based on ESC of the present invention includes:
[0039] Step 1. Calibrate according to the corresponding frequency and power in the full frequency band and full power range of the signal source, and establish a two-dimensional frequency agile signal frequency response calibration array;
[0040] Step 2: When starting up, store the calibration data in the corresponding storage area of the two-dimensional frequency agile signal frequency response calibration array according to the frequency and power index;
[0041] Step 3: When the frequency or power of the agile signal changes, the main controller is used to fetch the corresponding calibration data from the storage area of the two-dimensional agile signal frequency response calibration array according to the frequency to be switched to;
[0042] Step 4: Calculate the current corresponding frequency response compensation data according to the calibration da...
