Abstract :
A new class of controllable reflective type antenna arrays is considered, made as microstrip integrated circuits with arbitrary-shape microstrip radiators and controlled elements (crystal diodes). Electromagnetic characteristics of the array are varied by tuning the diode bias voltages. For a digital control possibility, all microstrip radiators are divided into several groups (modules): Each module can be at least in two electromagnetic conditions which are defined by the diodes states (open or closed one). The array controlling is carried out by a microprocessor. The digital array probable states number is proportional to the number of modules and each module allowable conditions number. Digital diffraction reflect-array has a set of microwave radar images whose changing enables one to create so called “intellectual covers” capable to adapt for radar-tracking environment
