two-row method

A new material surface modification method, or cold spraying technology, is introduced. In this way, the coat is deposited on the target by supersonic two phase flow at normal temperature or in a little bit heated gas.

介绍一种新型材料表面改性技术&冷喷涂技术，即气体在常温下或在有限加热温度下，利用超音速气流将涂层粉末喷射到基板形成保护涂层。

This method has two advantages: first it is cheaper and second it is quicker.

这个方法有两个优点：一是更便宜，二是较快。

This new method can obtain the direction of the target with phase information of two orthogonal interferometers on the observer and the radial distance with the corresponding phase rate of change. Then the target can be located with high speed and precision.

该方法利用观测平台上两个相互正交的相位干涉仪接收目标辐射电磁波的相位获取目标的方向信息，利用对应的相位变化率获取目标的径向距离信息，从而实现对目标的实时高精度定位。
