一、引言在机载前视多功能雷达的空/海搜索方式(或称海Ⅱ搜索方式)中,雷达以低脉冲重复频率脉冲体制工作,可采用频率捷变技术对海杂波进行抑制,并利用脉冲压缩技术提高雷达探测性能。普遍认为,利用频率捷变和脉压技术在中等海情以下搜索发现海面目标具有较佳性能。雷达探测海面目标时,海浪杂波便成为一种干扰,它和接收机噪声共同构成检测目标的
I. INTRODUCTION In airborne / sea search (or sea search method) of multi-purpose radars in airborne forward looking multi-function radar, the radar operates with a low-pulse repetition frequency pulse system and can suppress the sea clutter by using frequency agile technique. And use pulse compression technology to improve the radar detection performance. It is generally accepted that the use of frequency agility and pulse pressure techniques to search sea surface targets below moderate sea conditions has better performance. When the radar detects the sea target, the clutter becomes a kind of interference, which together with the receiver noise constitutes the detection target
