표 1. | Table 1. 완전디지털배열과 능동위상배열 특징 비교[3] | The comparison between full digital array and active phase array.

Attribute Active phase array (analog active array) Full digital array (element level digital)
Beam shape flexibility Fixed beam shape Fully reconfigurable shape
Multiple simultaneous receiving beam Very few limited by beamforming complexity Multiple, independent limited only by element pattern
Jamming and interference signal suppression Low sidelobe tapers SLC using auxiliary receiver Low sidelobes fully flexible adaptive cancellation
Instantaneous dynamic range Dynamic range of receiver System dynamic range = dynamic range of receiver ÷ number of receiver
Linearity (mainbeam, sidelobe) Low on mainbeam high on sidelobe Constant with beamforming gain or angle
System phase noise Phase noise of exciter System phase noise = phase noise of exciter × number of exciter
Angle accuracy Typical (conventional monopulse) Somewhat higher (multiple simultaneous receive beams)
