| 摘 要： | 针对高频地波雷达中的非均匀噪声环境及各种干扰源时变的特点,提出构建一种时变白化滤波器。先对非均匀噪声环境进行白化处理,然后在一维恒虚警的基础上,采用一种基于多普勒频率和距离的二维恒虚警处理算法。实验结果表明,利用时变白化滤波进行处理后,再在距离和多普勒频率维同时进行恒虚警检测,可以得到较好的检测结果。

| Abstract: | According to the time-varying properties of the disturbances which exist in high frequency ground wave radar,we propose a new algorithm of two-dimensions constant false arm rate based on Doppler and range spectrum.The nostationary background is whited with time-varying filter.The three results are compared such as time-varying whitening and two dimension processing,fixed whitening and two dimensions processing,no whitening and one dimension processing.The new algorithm is valued correctly with the comparing results. |
