【摘要】 米波雷达的工作波段内存在窄带干扰信号,其功率与雷达目标回波相当甚至更强,严重影响目标信号的检测。提出一套抗窄带干扰系统方案,完成干扰检测、抑制和脉冲压缩等功能。系统以FPGA与高速DSP为核心,具有较强的稳定性和灵活性。外场实验数据表明,该系统能实时有效地检测并抑制干扰,达到预期的效果。更多还原

【Abstract】 The working waveband of meter-band radar crosses with some narrow band signals,which are usually stronger than target echo and affect the detection of target greatly.A real-time anti-jamming system based on FPAG and DSP is designed accomplishing jamming-detect,suppression,pulse compression and so on.The system is stable and flexible.Anticipative effect can be achieved through outfield-experimental data.更多还原
