摘要
高频地波雷达一般采用线性调频连续波的信号体制 ,用去斜率的方法进行解调处理 .本文根据这种雷达的接收机工作原理 ,提出了一种新的接收系统补偿方案 ,即把系统补偿分为宽带补偿和窄带补偿两部分 ,分别在时域和频域完成 .文中对时域宽带补偿这种新方法在理论上作了严密的论证 。
High frequency ground wave radar generally adopts linear frequency modulated continuous wave (LFMCW) signals as the transmitting signal and acquire demodulation by getting rid of the slope.Here a new receiver system compensation scheme is proposed according to the working principle of this kind of radar.The system compensation is divided into wide-band compensation and narrow-band compensation,which are accomplished in time domain and frequency domain respectively.Rigorous theoretical demonstration and computer simulation results are brought forth in this article for the new method of wide-band compensation in time domain.
