当时的雷达在夜间或者不良天气下起到重要作用,但是注意:并非直接指挥火炮打击,而是探测,搜索敌人,在直接指挥炮击上甚至直到50年代,仍然有诸多不理想的地方。
北角海战,公爵对沙恩取得较多的命中是在后者被驱 ...
只能探测搜索有什么来源根据? 也就是日本雷达而已吧。老早就给了KGV的日志。
KGV got an echo with her Type 284, setting the initial range at 25,100yards and relayed this range to Rodney. Rodney used this range to goodeffect. KGV accidentally ranged on the radar reflections of Rodney's shell splashes so did not get on target until 0910 when she scored witha concentrated shell salvo. She continued firing under radar rangingusing the Type 284 until 0913 when the set broke down.
当然如果指挥配合得当,雷达员识别水溅信号在多舰射击也可以很好。如苏里高西弗吉尼亚的报告:只有第5次齐射的信号受其他舰干扰。

The MK 8 radar operators had no difficulty in identifying or spotting our salvos. Splashes from other ships were observed but did not interfere except on the 5th salvo.
如果对雷达测水柱有疑问,还可以参考这个:

Even in perfect weather, optical spotting deteriorated rapidly beyond 18,000yards; in comparison with the Mark 8 mod 0 fire control radar could spot 16-inch splashes out to about 20,000 yards and the improved Mark 8 mod3 could reliably spot 14-inch and 16-inch fire out to at least 35,000. The Mark 13 radar was even better yet. Officers testing the equipment aboard USSIowa in 1945 would write:
"Spotting both 5-inch and 16-inch splashes, HC or AP, with the Mark 13 radar is comparable to deliberately drawing a picture of the splashes on paper and looking at it. At all ranges fired during this period, the most inexperienced officer, givena brief explanation of what to expect, can spot splashes accurately towithin 100 yards, and to within 50 yards with some experience."
那时候雷达当然不能说完善,KGV就把罗德尼水溅雷达信号当了自己打的。库拉那种乱哄哄的战斗,对小目标也不是很理想。但大舰洋上单挑情况就简单多了。
还有库拉海战,海伦娜自己的炮弹出了问题,无焰炮弹正好用完。
The U.S. ships opened fire at 01:57 and quickly sank the destroyer Niizuki and killed Admiral Akiyama. However the Helena had expended all its flashless powder the night before and was forced to use smokeless, illuminating itself to the Japanese ships with every salvo.
