1 | The algorithm can effectively estimate the target's bearing and have good robustness by the model of plane wave. | |
2 | Meanwhile, these results are compared with those obtained under the plane wave approximation and some related questions are discussed. | |
3 | In this paper the positions of images reconstructed by illuminated plane waves of Fraunhofer defocused holographic memory system are theoretically described and discussed. | |
4 | For the transient spatial response, it is possible to obtain a parallel acoustic beam by eliminating the edge wave, and a long axis focusing beam by eliminating the plane wave. | |
5 | Group theory is introduced into the calculation of photonic band gap with the plane wave expansion method, and improved calculation formulae are derived. |
