Abstract: | At their long-range mode, conventional magnetron-based marine radar use low pulse repetition frequency (PRF) to extend the unambiguous range, and increase the pulse-width to regain the average power. The proposed new waveform maintains narrow pulses and high PRF even at the long-range mode. Range ambiguity is mitigated by periodic `yes`no` coding of the transmitted pulse train. Using narrow pulses improves the range resolution and reduces the radial dimension of the illuminated clutter. |
