The invention discloses a method for converting an L-shaped linear array into a planar virtual array. The method comprises the steps of building a space rectangular coordinate system xoy-z, enabling receiving antennas to be arranged along an x axis and a y axis, and forming the L-shaped linear array, constructing virtual array elements on the basis of the L-shaped linear array to form a virtual area array, and calculating the position and angle from the target to any array element of the virtual area array through geometric analysis by utilizing the position and angle relationship of the target on the array element of the L-shaped linear array, and completing the conversion from the L-shaped linear array to the planar virtual array, thereby realizing the same performance as a real array element. The virtual area array is generated on the basis of the L-shaped linear array, so that the number of array elements is reduced, the technical barrier that a traditional area array is realized by depending on a large number of entity array elements and complex hardware is broken through, and the problems that a planar array is complex in structure, high in power consumption, high in cost andthe like are fundamentally solved.
