【摘要】 通常在进行测向时,多使用MUISIC方法进行来波估计,但是在进行数据处理时,常使用复数数据进行特征分解及谱峰搜索。当搜索点数较小时,其运算量还在接受范围,但是当对谱函数的精度要求较高时,必然只能增加搜索点数,在这种情况下,该方法在硬件实现时,其运算量将会很大,所以寻找一种能够减小运算量的方法是实现实际处理的需求,因此,在本文中将会结合圆环阵结构的特殊性以及快速变换的方法,分析其实际处理中的可行性。更多还原

【Abstract】 Usually,when performing direction finding,the MUISIC method is often used for the direction of arrival.but when we process the data.we usually use the complex to feature decomposition and search the peaks,when the points that we need is enough small,the amount of calculation we can accept.but in another hand,if we need the higher accuracy of spectral function,the only way that we could use is enlarge the points of search,so,in this situation,it wiil be very difficult to achieve in the hardware,thereforefi nd a method that have less calculation is the requirement in actual implementation.so,contrary to the characteristic of circle array and the method of fast transform,com bine these two side,and analyze the feasibility in the actual treatment.更多还原
