摘要
目标特性测量雷达一般采用宽窄带交替的工作方式,宽带用于获得目标高分辨特征信息,窄带用于目标检测和跟踪。如果雷达只采用宽带工作方式就能够既进行目标检测和跟踪,又能获得目标高分辨特征,则可以降低雷达系统的复杂性,并节约雷达的时间能量。文中提出了一种基于雷达宽带回波的目标测量方法,该方法利用多个宽带回波的幅度和相位信息测量目标距离和速度,实际数据的实验结果验证了该方法具有较高的测距和测速精度。
Target characteristics measurement instrumentation radars commonly adopt alternative wideband and narrowband working modes. The wideband mode is used to obtain target high resolution characteristic, and the narrowband mode for target measuring and tracking. If the radar can apply only wideband mode to carry out target measuring, tracking, and also high resolution characteristic obtaining, the complexity of radar system would be decreased and the radar time-energy is saved. A method for target measuring based on wideband radar returns is proposed, which measures target range and velocity utilizing both the amplitudes and phases of multiple wideband returns. Experimental results using real data validate high precision in range and velocity measuring of radar.
