Abstract :
This paper addresses a half distributed solid state array radar system, which uses 54 L-band power amplifier modules (2.0 kW output power). The total space combination power of this system can reach up to 100 kW for a 150 μs pulse width at 8% average duty cycle with a 14.5% instantaneous bandwidth. A switching power supply and liquid cooling have been employed to achieve good performance and stable reliability. Such a system has already been utilized in a three dimensional high performance radar
