Embodiment Construction
[0045] The present invention will be described in detail below in conjunction with specific embodiments. The following example is taken as an example to illustrate the present invention, and the present invention can be extended to other matrix and antenna arrangement structures.
[0046] Embodiments of the present invention are as follows:
[0047] The basic array in the example of the present invention is a 12-element linear array, which is composed of M array elements evenly arranged, wherein M represents the number of array elements, the transmission signal is a single-frequency pulse, and the processing environment is broadband.
[0048] Such as figure 1 Shown is a flowchart of an adaptive beamforming method according to an embodiment of the present invention, which includes the following steps: firstly, transmit single-frequency pulse data is provided, and then complex demodulation and data rate reduction are performed. In this example, in order to reduce the amount of...
