摘要
数字控制的自适应频率捷变雷达可灵活准确地控制每一个相继脉冲的频率差都大于临界频率，使所有的脉冲都是独立的，海杂波完全去相关．实验测得海杂波被抑制了５．８ｄＢ；对海杂波背景中的小目标作用距离增加３．８倍，都接近理论值．分析表明，自适应频率捷变雷达能很好地满足在海杂波背景中，对小目标侦察警戒的战术技术要求．
All pulses are independent and the reletivies of sea clutter are gone because the radar of noncoherent adaptive frequency agility by digital controlling can control a fine frequency difference of a pulse next to another pulse,which is large than critical frequency.The sea clutter jamming is suppressed by 5.8 dB while the radar range has increased by 3.8 times by comparing frequency agility radar with constant frequency radar for small target in sea clutter.The data above are detected by experiments. These data approach theoretical values.As is shown by analysis, the radar can satisfy requirement for military tactics and technique of reconnoitering and warning small targets in sea clutter.
