Martello S 743
The planar antenna consists of laser-cut horizontal linear Elements vertical stacked, each its own receiver. Ultra-low sidelobes are achieved by precise control of the phase and amplitude fed to each element. The array is driven by a number of distributed solid-state transmitter modules whitch are phase controlled to give a highly adaptable beam shape in elevation.
Every target within the elevation cover is illuminated on every transmission. Signal returns are combined to form simultaneous overlapping stacked vertical beams, tailored to suit the operational requirement. High accuracy elevation data is derived by monopulse processing of signals in adjacent beams.
A unique new signal processor provides MTD or MTI modes to suppress simple or bimodal clutter, automatically controlled by a clutter map. Parallel coherent processing is carried out simultaneously at all ranges and elevations without reduction of data rate. Signal processing functions are performed by an array of identical modules, each of whitch can perform any of the required task.
Intelligent BITE automatically replaces a failed module with a redundant unit.
An integral SSR/IFF system, with Mode 4 capability, enables correlated primary and secondary radar plot data to be passed to operations centers.
