(54) СПОСОБ ИЗМЕРЕНИЯ НАПРЯЖЕННОСТИ ЭЛЕКТРОМАГНИТНОГО(54) METHOD OF MEASUREMENT OF ELECTROMAGNETIC TENSION
ПОЛЯFIELD
угловой скоростью вокруг оси, совпадающей д направлением максимума приема. Наведеиный сигнал на выходе аитенны модулируетс путем вращени аитенны по периодическому закону, детектируетс и Ьодаетс в отсчетиы блок, где сравниваетс с опорным сигналом. При этом измер етс интервал времени t превышени продетектированиого сигнала над величиной опориого сигнала и определ етс величина напр женности пол Е по формулаangular velocity around the axis coinciding with the d direction of the maximum reception. The navidine signal at the output of the antenna is modulated by rotating the atienno according to a periodic law, a block is detected and b measured, and compared with the reference signal. In this case, the time interval t of the detection signal over the value of the reference signal is measured, and the strength of the field E is determined by the formula

Т - период вращени антенны. T is the period of rotation of the antenna.
Применение предлагаемого способа измере ни напр жениост электромагнитного пол позвол ет расщиритъ динамический диапазон и уменьшить погрешн стъ измерений.The application of the proposed method for measuring the voltage of an electromagnetic field allows the dynamic range to be broadened and the measurement error to be reduced.
Нижний предел измерени определ етс порогом чувствительности детекторе в совокупности с отсчетным блоком, а верхний предел - предельно допустимым уровнем сигнала, рассеиваемого детектором. Динамический диапазш достигает пор дка 100 дБ.The lower limit of measurement is determined by the sensitivity threshold of the detector in combination with the readout block, and the upper limit is determined by the maximum permissible level of the signal dissipated by the detector. The dynamic range is in the order of 100 dB.
