摘要
天基预警雷达的空中运动目标指示(AMTI)在军事上有着极其重要的应用价值,然而常规线性调频波形在面对复杂距离和多普勒模糊时数据搜索率较低,相干积累脉冲数较少,杂波抑制和抗干扰能力较弱。在美国L波段天基预警雷达系统的基础上,着重研究了天基AMTI雷达近端、中端和远端探测时的合成宽带波形设计要求,并通过合成宽带信号处理仿真验证了其在高速弱空中动目标检测中具有优良的性能。
Aerial Moving Target Indication(AMTI)carried out by the space-based early warning radar has great significance in military applications.However when confronted with severe range ambiguities and Doppler ambiguities the conventional Linear Frequency Modulation(LFM)waveform has low data search rate few coherent pulses and weak clutter-suppression and anti-jamming capabilities.In this paper the design requirements of the synthetic wideband waveform for space-based AMTI radar detection at near middle and far range are researched on the basis of the American project known as L-band Lightweight Space Based Radar(LLSBR).The simulation results of synthetic wideband signal processing show that the synthetic wideband waveform has excellent performance in the detection of high-speed weak aerial targets for space-based AMTI radars.
