| titleOfInvention | Double-hole co-prime array antenna structure |
| abstract | A dual-hole co-prime array antenna structure is composed of four sparse sub-arrays, the total number of array elements is T, the number of antennas is N, And M, wherein N and M are relatively prime integers, and M < N. The array element position in the CATHDC antenna structure is Wherein And d is less than or equal to lambda/2 which is the unit array element spacing, lambda is the carrier wave length, the antenna structure of the invention expands the aperture of the antenna, weakens the mutual coupling effect, has simple antenna array layout and can obtain the degree of freedom higher than the existing co-prime array. The virtual array generated by the CATHDC is a uniform array of unit array element spacing, a classical signal arrival angle estimation algorithm can be directly applied by combining a space smoothing method, and the problem of angle ambiguity cannot occur. |
