Application of the Resistive Sensors for High-Power Nanosecond Duration Microwave Pulse Registration

Abstract

Resistive sensor for high-power nanosecond duration microwave pulse registration has been tested under the operation conditions. The response time of the resistive sensor has been estimated using the time domain reflectometry method. Our investigations have demonstrated some advantages of the resistive sensor over the calibrated diode that is usually employed for microwave pulse power measurement. It can detect about 60dB higher pulsed microwave power, is resistant to larger power overloads, produces high output signal and is sufficiently fast to measure nanosecond duration high power microwave pulses.
