摘要
本文从地震资料的质量、投资成本和施工灵活性等几个方面阐述了单道与多道遥测系统结构的优缺点。还着重论述了直升飞机支持的地震队在同一探区采用单道或多道采集站时,选择遥测系统类型时必须要考虑的因素。
In this paper the advantages and disadvantages of telemetry system with single channel and multi-channel per ground unit will be shown not only in terms of seismic quality but also in terms of capital ex-penditure and operation flexibility. An interesting example of heliborne crew using single and multi-chan-nel per units in the same prospect confirms that all the above mentioned parameters must be taken into consideration when selecting the type of telemetry system.
