【 摘 要 】

In order to solve the current difficulty of radiation calculation of current missile phased array radar arrays, the elemental radiation pattern of small arrays is used to calculate the unit radiation field in a similar environment in large arrays by the element active pattern equivalent method, and then the superposition theorem is used. Calculating the total radiation field of the large array avoids matrix operations in the calculation process and reduces the amount of calculation. And the linear array is extended to the missile-mounted phased array radar antenna array. The radiation pattern of a certain type of missile-loaded phased array radar antenna array considering mutual coupling is calculated. The obtained radiation pattern is in good agreement with the far field test results. The comparison with the far field experiment shows the effectiveness of the method.
