摘要
在成熟的数传电台技术设备基础上,开发出高速的调制解调器,凭借计算机超强的图像接收处理能力,研制出性能价格比优越的机载图像无线传输系统。经检验,该系统各项指标如下：①数据传输频段为220-240MHz;②传输方式是点对点、点对多点传输;③信息形式为图像和话音;④数据传输率为2.4、4.8、9.6 kbps,最大为19.2 kbps;⑤传输误码率≤1×10-6;⑥射频功率≤25W;⑦传输最大距离≥70 km。
Based on the mature digital radio technology and equipment,we have developed a high-speed modem.Relying on computer super image receiving handling capacity,we also have developed performance superior airborne image wireless transmission system.Through examination,the system can satisfy each index better in the existing aviation forest protection main model and the needs of ground watchtower information on fire.Index as follows：①the data transmission spectrum：220~240MHz;②transmission mode：point-to-point,point-to-multipoint transmission;③information form：image and voice;④A data transfer rate：2.4 kbps,4.8 kbps,9.6 kbps,maximum 19.2 kbps,⑤transmission error：≤1×10-6;⑥rf power：≤25W;⑦Indirectly affect the transmission distance：≥70km.
