Resistive sensor for high power microwave pulse measurement

A resistive sensor (RS) devoted to the measurement of a high power microwave (HPM) pulse is presented. The performance of the RS is based on electron heating effect in semiconductor. It can measure HPM pulses directly; it is resistant to large power overloads and demonstrates very good long-term stability. The RS can produce an output signal of the order of a few tens of Volts without any amplification circuit and it can be done sufficiently fast to measure nanosecond duration HPM pulses. In this paper, different types of the RS developed, manufactured and tested in our laboratory are presented
