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) |
