| 摘要 |
According to this invention, an electronically scanned radar antenna array is rapidly scanned over a plurality of adjacent beam positions, to avoid the possibility of fast-moving targets escaping detection. The radar PRF is increased to yield the same unambiguous range and target echo sensitivity compared to a slow-scan system. In a modification of this concept, rapid interlaced scanning is provided to reduce the probability of second-time-around echoes entering adjacent beam positions.
