A novel HPM array system based on mode locking multi-frequency

HPM systems fall into two general categories. The first uses moderately high power, quasi CW sources in the MW range with pulse duration around a millisecond and are generally of narrow bandwidth but with large average power. In the second category we have very high Peak power - in the GW range, but of very short pulse duration, typically in the 100ns range, and are of a large bandwidth. These sources, due to their pulse power technology are limited in average power and pulse repetition frequency. Some HPM applications require beam steering either by mechanical means or by phasing an array. Some applications, such as counter electronics, require the continuous sweeping of the beam over a large forward area. Sweeping arrays require phase shifters that are costly and difficult if they are required to accommodate a large bandwidth and Power.
