Transmitter Output Power Control of PCMC Radar for Short Range Tracking Bypassing Cross-field Amplifier

Abstract

This paper presents a novel method to control the transmitter output power of PCMC (precision coherent monopulse C-band) radar by isolating the CFA (cross field amplifier) stage of MOPA (master oscillator power amplifier) chain. The isolation is achieved by switching mechanism in case of short-range tracking and it provides signal amplification in long-range tracking. The proposed scheme also reduces CFA operation time and TWT (traveling wave tube) output load.
