| 发明名称 | Radar beam sharpening system and method | ||
| 摘要 | A radar beam sharpening system for processing a radar video stream of echo return intensities, sampled in range and azimuth. The system uses a signal processor that is configured to apply beam sharpening to the radar video stream and which selectively varies the level of beam sharpening applied as a function of range and/or a land map generated from the radar video stream so as to generate an output selectively beam sharpened radar video stream. | ||

| 主权项 | 1. A radar beam sharpening system for processing a radar video stream of echo return intensities, sampled in range and azimuth, comprising: a signal processor configured to apply beam sharpening to the radar video stream and to selectively vary the level of beam sharpening applied to samples of the radar video stream based on their respective ranges so as to generate an output range-dependent beam sharpened radar video stream, wherein the signal processor is configured to reduce the beam sharpening applied for at least a portion of shorter ranges relative to longer ranges. | ||
