Abstract
A receiving arrangement for a pulse radar tracker facilitating low elevation angle tracking. The received signals are sampled along the focal plane of the receiving antenna system aperture. Range gating at IF and delay line serialization are provided to generate a simulated (synthetic) scan of the aforementioned aperture plane in the form of a coherent signal waveform. The main lobe of a multipath (ground reflection in the elevation case) is substantially eliminated by the time gating and filtering is provided to greatly reduce the corresponding sidebands. Desired (direct) received signals are substantially unaffected.
