实验和理论研究了混沌激光雷达的抗干扰性能。利用光反馈半导体激光器混沌激光雷达样机，分别研究了其对混沌激光信号、连续波调制雷达信号和脉冲雷达信号的抗干扰能力。实验与数值模拟结果表明，在不采取任何抗干扰措施的情况下，混沌激光雷达对同种体制混沌信号干扰以及不同种体制的正弦调制激光信号和脉冲激光信号干扰都有较大容忍限度，具有天然的抗干扰能力，且其测距精度在混沌激光雷达样机量程范围内不受干扰信号影响。分析了利用简单平均算法进一步提高混沌激光雷达抗干扰性能的可行性。

Anti-jamming performance of a chaotic lidar is investigated experimentally and numerically. Using our chaotic correlation range-finder prototype, the anti-jamming capabilities of the chaotic lidar to different undesired signals are studied. Experimental and numerical simulation results indicate that the chaotic lidar, which takes no anti-jamming measure, possesses natural anti-jamming ability and larger noise tolerance to the disturbance from the chaotic laser, continuous-wave modulation laser and pulse laser signals. The feasibility of improving the anti-jamming performance of the chaotic lidar by using an average algorithm is analyzed.
