A multiple-target-detection technique based on phase processing of data collected in a sequential mode operation is presented. The elements are assumed to be circular dishes. No tapering or phase-shifting hardware is needed. The firing of the elements is sequential with all or some of the elements receiving in parallel. The sequential operation and phase processing applied to a real array show a significant improvement in the array pattern. However, the attenuation of the secondary patterns is not sufficient because the diameter of the dish is limited by the element spacing. the secondary patterns can be reduced to an acceptable level using bistatic arrays. In the present application, the bistatic array consists of two adjacent linear arrays: one transmitting array with large dishes and spacing, and a receiving array with small dishes and spacing
