Abstract

We present the results of a study of high-frequency artificial ionospheric turbulence generated by the low-latitude heating facility at Arecibo Observatory (Puerto Rico, USA) on November 7–9, 2018, using incoherent scatter radar to measure the plasma line (PL) and stimulated (or secondary) electromagnetic emission from the ionosphere (SEE). The ionosphere was pumped by a high-power radio wave of ordinary polarization with effective radiation power P_eff ~ 100 MW emitted vertically upward at the pump wave (PW) frequency f₀ = 5095 kHz. A comparison is made between spectra and dynamics of the PL and SEE during the first five seconds of pumping.

2018年阿雷西博加热设施实验电离层受激电磁发射等离子体线时空演化与时间变化抽气的前五秒

作者于2018年11月7日至9日，利用非相干散射雷达测量电离层等离子体线（PL）和受激（或二次）电磁发射（SEE），对美国波多黎各阿雷西博天文台低纬度加热设施产生的高频人工电离层湍流进行了研究。以泵浦波频率f0 = 5095 kHz垂直向上发射有效辐射功率Peff ~ 100 MW的普通极化高功率无线电波对电离层进行泵浦。比较了抽运前5秒内PL和SEE的光谱和动力学。
