A controlled experiment on the nonlinear wave-wave interaction in the ionospheric plasma was performed by the Japanese sounding rocket K-9M-35 in 1971. The object of the experiment is to investigate a feasibility of on artificial realization of the most fundamental three wave process between two electron plasma waves and one ion acoustic wave in the ideal plasma in the ionosphere. A high frequency electric field was applied between two grids exposed on the plasma in order to transmit the first electron plasma wave (or oscillation). Detection of the second electron plasma wave and the ion acoustic wave was made by a probe stretched between the grids. The frequency (or energy) relation of the three wave decay process is ckecked by phase sensitive detectors together wide band reception of the ion acoustic wave. The ckeck of the wave-numbes (or momentum) relation was not performed for want of the weight and space of the equipment. The experiment was accomplished completely throughout the flight and we gathered much information about the dependence of the three wave decay process on the transmitting frequency, the local plasma parameters and on the DC-bias imposed on the receiving probe. The results are : (a) An excitation of the ion acoustic wave by the above three wavs process is observed at a limited height in the ionosphere, (b) The process is closely related with not only the local plasma frequency but also the DC-bias of the probe, (c) A frequency spectrum of the ion acoustic wave depends on the local plasma frequencies and shows complex forms like risers and inverted hooks. A comprison of the experimental results with a theory of the three wave process by Nishikawa is also made. |
