Recently Dr. Daniel Kaminski wrote into RTL-SDR.com to let us know about two very interesting new SDR# plugins that he has developed to use with the RTL-SDR dongle. The first plugin is called “Passive Radar”. Passive Radar allows you to use an existing strong transmitter such as an FM station to detect reflections from things like aircraft and meteors. Dr. Kaminski writes about his plugin:
The first one is passive radar which bases on signal from one dongle. The ambiguity function is the same as in advanced projects with the difference that the one I implemented is self-correlated one instead of cross-correlate one used for 2 dongles projects. In internet can be found that such solution theoretically can works. If the reflected signal is comparable in strength to the reflected one. This plugin is still until development.
In the future he hopes to be able to support two dongle passive radar as well.
The second plugin is called “IF Average”. This plugin allows the IF signal to be averaged which is useful for radio astronomy projects such as detecting the Hydrogen line. He writes:
The second plugin which is finished is for IF signal averaging. It is important in case of radio-astronomical observations. It allows to cumulate signals (up to 10000 samples in real time), present them in friendly way and save for further work.
