研究目的
To lower the peak sidelobe level of a two-way array factor using uniform transmit and uniform receive arrays with different numbers of elements without amplitude tapering.
研究成果
The paper demonstrates a method to lower the two-way pattern peak sidelobe level by using uniform transmit and uniform receive arrays with different numbers of elements. This approach results in a modest reduction in peak sidelobe level at the expense of a slight decrease in directivity, applicable to both linear and planar arrays.
研究不足
The approach results in a decrease in directivity while lowering the peak sidelobe level. The exact trade-off between directivity and sidelobe level reduction may vary based on the specific configuration of the arrays.
1：Experimental Design and Method Selection:
The study uses mathematical representation of transmit, receive, and two-way array factors of uniform linear arrays.
2：Sample Selection and Data Sources:
The study considers uniform linear arrays with different numbers of elements.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned.
4：Experimental Procedures and Operational Workflow:
The approach involves setting the first null of one aperture to be in the same direction as the peak sidelobe of the other aperture by having a different number of elements in the two apertures.
5：Data Analysis Methods:
The study analyzes the directivity and peak sidelobe levels of the resulting two-way patterns.
