声光技术在雷达动目标模拟中的应用， 由于受到延迟时间固定不变或只能离散变化的限制,许多雷达目标模拟器不能模拟连续运动目标的变化。为此,设计了一种新型的声光延迟系统,并对该系统的性能作了分析。与其它延迟系统相比,本系统的优点在于延迟时间可连续变化,延迟总时间可满足信号处理的要求。因此,它可以方便地应用于运动雷达目标模拟和其它信号的处理。 (Sound and light technology in radar moving target simulation, due to the limit of the delay time constant or only discrete changes, many radar target simulator can not simulate changes in the continuous moving target. To this end, the design of a novel acousto-optical delay system, and the performance of the system analyzed. Compared with the other delay system, the advantage of this system is that the delay time can be continuously changes to delay the total time can satisfy the requirements of the signal processing. Therefore, it can be easily applied to the sports radar target simulation, and other signal processing.)

述是经典MUSIC算法的基本原理，许多限制是可以放宽或取消的。首先，关于均匀线阵的限制不是必须的，实际中可采用几乎是任意形状的阵列形式，只要满足在个独立信号源的条件下，矩阵具有个线性无关的列就可以了。其次，天线阵元在观测平面内无方向性这一点也不是必要的，而且还可以考虑三维空间的DOA估计问题，即不仅估计信号的方位角，还要估计它的俯仰角，当然MUSIC算法还用于频率、方位和俯仰的联合估计。(Above is the basic principle of the classical MUSIC algorithm, a number of restrictions can be relaxed or canceled. First, restrictions on ULA is not necessary, the actual form of an array can be almost any shape, as long as the signal source in the independent condition matrix has linearly independent columns on it. Second, the antenna elements in a plane non-directional observation it is not necessary, but could also be considered DOA estimation of three-dimensional space, that is not only estimated azimuth signals, but also to estimate its pitch angle, of course, also MUSIC algorithm joint estimation for the frequency, the azimuth and elevation.)
