| Abstract: | A novel received beam forming method based on stretch processing and phase compensation in the presence of wideband signal and large scanning angle is presented, and the realization chart is given. Compared with the basic processing methods in time domain and frequency domain, the new approach is simple computationally and demands fewer equipment. Moreover, it can reduce the bandwidth of the received signal, and is easily implemented in practical engineering. Computer simulation result demonstrates the effectiveness of the proposed method. |
| Keywords: | Large scanning angle Wideband beam-forming Stretch processing |
