| 摘 要： | 在阐述FFT方法、最小二乘曲线拟合方法和雷达信号特点的基础上,将BP网络应用于线性调频连续波雷达系统目标距离的信号处理中,用雷达数据对构造的BP网络进行了训练和测试。仿真结果表明,该方法在训练对象足够充分的情况下可以适应较大范围内测量,在无噪或低噪声的情况下,可以获得较高的测量精度,是一种对LFMCW系统信号处理的有效方法。

| Abstract: | Based on the method of FFT,the least squares and characters of radar signals,the BP(Back-propagation NN) was applied in the signal processing of object distance in LFMCW system,trained and tested the BP network with the radar data.The result of the emulate experiment showed that this new method could be used to measure in greater range if the training objects were enough,in the case of no noise and low noise,it could gained high measuring precision,thus,this is an effective method to process the signals of the LFMCW system. |
