Research on Spatial Power Combining Efficiency of High Power Radar

The spatial power combining efficiency of high power microwave（HPM） is directly relevant to output power of high power radar. The paper mainly researches the spatial power combining efficiency of high power radar. Firstly, a formula of the spatial power combining efficiency is deduced. Then, the influence factors on synthetic efficiency is analyzed, such as phase error, target position error, delay error, and the array element spacing error and so on. Finally, it presents an amplitude-phase joint regulation method. The amplitude~phase error between channels is reduced by adding amplitude and phase adjustment circuits, and the HPM spatial power combining efficiency is impoved.
