摘　　要：该文根据超混沌映射初值敏感性、内随机性和高维超混沌等特点,提出了一种新的脉内混沌调相-脉间随机编码的SAR信号。文中详细比较了4种超混沌映射调相信号的特点,并在此基础上选择了超混沌Logistic映射调相信号作为SAR发射信号,仿真实验表明,这种信号的确具有高保密性和较强的抗干扰性能。In this paper, a new Synthetic Aperture Radar（SAR） signal of chaotic phase modulated intra-pulse and random coded inter-pulse is porposed depending on the characteristic of extreme initial value sensitivity and pseudo-randmoness and multidimensional hyperchaos. Four hyperchaotic phase modulated signals are compared detailedly and hyperchaotic logistic map phase modulated signal is proved to be best for SAR transmit signal. This signal is proved with an excellent exhibition on encryption and high Electronic Counter CounterMeasures（ECCM） performances,
