← ScienceWhich risk increases when a phased array radar operates near 100% duty cycle?
A)Increased thermal runaway in amplifiers✓
B)Reduced antenna beamforming precision
C)Enhanced spurious harmonic propagation
D)Amplified atmospheric signal attenuation
💡 Explanation
Increased duty cycle in high power radar raises the average power dissipated, enhancing electron-phonon interactions. This causes the thermal runaway mechanism in amplifier semiconductors because heat cannot dissipate fast enough; therefore damage increases rather than precise beamforming under steady conditions.
