The design of reconfigurable antenna arrays using the method of vector space projections

The problem of element failure in antenna arrays is studied using the wellborn method of vector space projections (VSP). The use of VSP allows one to impose a set of desired constraints thru “alternating projections” to furnish a design of self healing arrays i.e. retrieving the sane performance, over the degraded one. By introducing a projection onto the set of dynamic range constraint(DRC), worthy results can be realized even in the case of 50% array element failure.
