51277 通过实例建模和试验数据对比,验证了所提方法的有效性。 By modeling and experiment data comparison, to verify the effectiveness of the proposed method.
51278 可匹配滤波混沌雷达系统可由低成本的模拟器件实现匹配滤波,受到广泛关注。 Can be matched filtering chaos radar system can be made of low cost of simulator to realize matched filtering, attracted much attention.
51279 但是该系统发射信号的带限性能不理想,信号在变换和传播过程中容易发生频谱泄露和畸变。 But the system transmitting band-limited performance is not ideal, signal is likely to occur in the process of transformation and spread spectrum leakage and distortion.
51280 针对该问题,提出一种基于混沌同步和滤波的波形设计方法。 Aiming at the problem, put forward a kind of waveform design method based on chaotic synchronization and filtering.
51281 该方法在雷达发射端,将混沌信号频谱整形为带限信号; This method in radar transmitter, the chaotic signal spectrum shaping for band-limited signals;
51282 在接收端,利用同步和滤波恢复出混沌信号。 At the receiving end, the use of synchronization and filtering out of the chaotic signal recovery.
51283 与传统在数字域上进行信号设计的方法相比,本文方法是在模拟域上实现的,具有低成本优势。 With the traditional signal in the digital domain design method, compared with the method are implemented in the simulation domain, a low cost advantage.
51284 此外,在信噪比低至-20dB时本文方法仍然有效, In addition, in low signal-to-noise ratio to 20 db - when the method is still effective,
51285 与直接匹配滤波相比,本文方法变换后的混沌信号匹配滤波后,最大旁瓣抬升很小。 compared with the matched filtering directly, the method after the transformation of chaotic signal after the matched filtering, side lobe largest lift is very small.
51286 运动目标检测是智能车辆动态环境感知中的关键问题。 Moving target detection is a key problem of intelligent vehicle dynamic environment perception.
