Modern Active Electronically Steerable Array (AESA) antennas offer substantial control over transmit and receive antenna beam forming, including via elemental weighting to achieve a desired tapered aperture. However, these tapers also have the adverse side effect of diminishing total transmitted power and/or raising the system noise figure. This is readily calculated, and must be considered for overall radar performance prediction. Independent tapers for transmit and receive arrays might be play.
