Height Measurement Accuracy Improvement Technology Based on Antenna Array Calibration

The invention relates to a height measurement precision improvement technology based on antenna array calibration, which adopts a theodolite, a static level-meter and a dynamic level-meter; Calibrating the true levelness by the theodolite, correcting the structural error in the data of the static level-meter by using the true levelness calibrated by the theodolite, installing the dynamic level-meter on the array. The theodolite is used to calibrate the system error of the dynamic level. The theodolite of the invention is used for calibrating the true levelness, utilizes the calibration true value of the theodolite to correct the measured values of the static level-meter and the dynamic level-meter, can correct the system errors of the static level-meter and the dynamic level-meter to a very small level. Thereby effectively improving the height measurement accuracy of radar.
