德国普拉特公司不仅生产VHF/UHF频段的测向系统,还生产HF频段的测向系统。事实上,普拉特公司的短波测向系统在国际上很受欢迎,德国的全国无线电频率管理机构RegTP使用的短波段测向系统就是普拉特公司生产的。普拉特的短波测向系统有宽带的和窄带的两种。其宽带的实时带宽可达2MHz,性能复杂,价格也比较高,这里我们简单介绍其窄带的产品DFP5050。
Germany Pratt not only produces the direction finding system of VHF / UHF frequency band, but also produces the direction finding system of HF frequency band. In fact, Pratt’s shortwave direction finding system is very popular in the world. The shortwave direction finding system used by RegTP, Germany’s national radio frequency management agency, is manufactured by Pratt. Pratt’s shortwave direction finding system has both wideband and narrowband. Its broadband real-time bandwidth up to 2MHz, complex performance, the price is relatively high, here we briefly introduce its narrowband product DFP5050.
