“…Calorimeter is unable to get the pulse waveform and instantaneous power. For lower energy pulses, it is difficult to carry out high precision measurements [4][5][6]. Diode detector is generally used for the measurement of power less than 1 W. When measuring HPM, it needs nearly 100 dB attenuation [7,8].…”

A real time measurement system without synchronised triggering was developed for the hot carrier detector. This system can measure the power and waveform of the high power microwave pulse. Based on the buck converter and the Wilson current mirror, it was composed of the voltage stabilising module and the constant current module. Unlike the original bias power supply which works in the pulse mode, a constant current about 20 mA can be continuously provided with the sensor. The system was tested by a X band hot carrier detector and a magnetron amplifier microwave source. With this measurement system, the microwave pulse of 50 ns–1 μs, 0.1–90 kW can be accurately measured. The output voltage of the hot carrier detector reaches 2 V while the input power equals 90 kW.

“…The RS can measure HPM pulses directly, produces high output signal, is overload resistant, and demonstrates very good long term stability [1]. The RS has proved to be a very convenient means of diagnostics in microwave electronics, especially for the measurement of short HPM pulses at a low repetition rate [2]. The typical experimental arrangement for such measurements is simple and flexible [2].…”

Interaction of a semiconductor plate with TE11 wave in a circular waveguide has been analysed for the purpose of optimizing a frequency response of a resistive sensor (RS). The performance of the RS is based on the electron heating effect and it is devoted to high power microwave pulse measurement. The semiconductor plate with contacts on its sidewalls serves as sensing element (SE) of the RS. A three-dimensional finite-difference time-domain method (FDTD) was applied to simulate wave propagation within a circular waveguide segment with the SE which is placed on a wall of the circular waveguide. The electric field distribution, voltage standing wave ratio (VSWR), and the average electric field dependences on frequency have been determined for several sets of dimensions and specific resistances of the SE. The parameters of the optimal SE were found.
