Several Calibration Methods for the Planar Phased Array Radar

Calibration is an important part of the radar debugging work. The calibration system undertakes the correction, calibration and compensation in the near-field debugging, far-field test and outfield joint test of the adar. Planar active phased array radar is widely used in land, air and warning radar. For different scenarios of radar debugging, the calibration system is illustrated in the paper. At the same time, the technique to reduce and eliminate the systematic errors is given. A sampling block is given to assist in the selection of sampling points. It is suitable for multiple forms of array of planar phased array antennas. A method of target tracking to validate the pointing accuracy is also given. This method can also verify the accuracy of the control code. The calibration method described in the paper takes the system scheme and practical operation as the main line, which complements the theory and simulation techniques of the existing literature to a certain extent.
