A miniaturized lightweight wideband null steerer

By using very lightweight hybrid microwave integrated circuitry, the size and weight of an analog, correlation-controlled, null-steering array atCband has been greatly reduced, to the order of 1 lb for a four-element array. The key components, the adaptive weights, and correlation control circuitry, have been demonstrated in miniaturized form, with a null depth of 25-30 dB attained over a 60-100 MHz bandwidth.
