Ajax, as the Web development community well knows, allows you to make asynchronous auxiliary requests to the server and display the resulting output directly on the Web page (see Figure 4).
It adopts space filtering technique to achieve suppression of jamming signal by comparing the output amplitude from the receivers of the main and auxiliary antennas.
它采用空间滤波技术，通过比较主、辅天线接收机的输出信号幅度，实现对干扰信号的抑制。

Using an adaptive process, the weights of the auxiliary antenna outputs are adjusted, and the interference in the main antenna output are estimated.
