| 摘 要： | 雷达导引头存在空间角分辨率低和角闪烁的问题,使得雷达导引头的制导精度比光学导引头差,为此,人们研究了仿形技术.频域仿形是仿形技术的一种,利用这一技术必须尽可能地提高毫米波雷达的多普勒频率分辨率.由于传统的FFT算法不能满足系统分辨率的要求,文中提出将ESPRIT算法用于估计频率,提高了频率估计精度和频率分辨率,仿真结果证明该方法是有效的.

| Abstract: | The problems of radar seeker are low angle resolution and angle glint,which makes guide accuracy of radar seeker,is lower than optical seeker's.Therefore,the profile model technique was researched.The frequency domain profile is one of the profile model techniques.If this technique is used,the frequency resolution of the millimeter wave radar seeker must be improved.The traditional FFT algorithm can not get higher frequency resolution,so the ESPRIT algorithm was proposed in this paper.This algorithm improve... |
