| Abstract: | The amplitude-comparison of sum and difference beams has been widely used in the radar system,as the method is easy to implement and has a high angular accuracy. The angle measuring technology and analyses of the angular accuracy are focused on. The total differential method is used to derivate the angle measurement precision of the method in the multiple-input multiple-output(MIMO)radar and the phased array radar, and a strict formula of the angle measurement error has been gotten, while the angle measurement accuracy of the two types of radars are compared under the same SNR conditions, and the analysis is verified by simulations. |
