先前已经表明，可以使用两种不同的配置，每种配置三个传感器，以相同的精度估计与目标的角度。配置为：1)一个投影仪和两个接收器，以及2)两个投影仪(发射正交波形)和一个接收器。在接收器复杂的情况下，第二种配置是理想的。这种交流表明，以前得到的结果可以推广到四个换能器的情况。也就是说，可以使四个换能器的三种可能组合，即：1)三个接收器，一个投影器，2)两个接收器，两个投影器，以及3)一个接收器，三个投影器，在角度估计方面具有相同的性能。众所周知，三个接收器的阵列可用于在干扰对象的方向上引导零点，从而允许估计感兴趣对象的角度。这里所述的三种配置是等价的这一事实意味着，例如，仅使用一个接收器和三个投影仪，就可以在干扰对象的方向上形成零点。
It has been shown previously that two different configurations of three transducers each can be used to estimate the angle to an object with the same accuracy. The configurations are: 1) one projector and two receivers, and 2) two projectors (transmitting orthogonal waveforms) and one receiver. The second configuration is desirable in the case where the receiver is complex. This communication demonstrates that the results obtained previously can be extended to the case of four transducers. That is, the three possible combinations of four transducers, namely: 1) three receivers, one projector, 2) two receivers, two projectors, and 3) one receiver, three projectors, can be made to have identical performance in terms of angle estimation. It is well known that an array of three receivers can be used to steer a null in the direction of an interfering object, thus allowing the angle of an object of interest to be estimated. The fact that the three configurations treated herein are equivalent means that one can, for example, form a null in the direction of an interfering object using only one receiver and three projectors.
