Research on high power microwave antenna gain measurement method

The paper presents several ways about antenna gain measurement. Based on high power microwave(HPM) antenna particularity, the change of antenna gain was studied under different pulse widths. The experiments were conducted using narrow pulse signal resource. The antenna gain values under narrow pulse were tested by the way of demarcating the received power under different pulse widths. The experiment shows that the test results are uniform in the cases of continued wave and narrow pulse wave. The experiment proves that HPM antenna gain measurement with pulse width more than 25 ns is as effective as continue wave measurement.
