In testing we found that the unit is solidly built and works perfectly. An interesting example of direction finding with three coherent RTL-SDRs can be seen in this previous post. A third example application is pulsar detection which we have seen in this previous post.Ĭ sent us a prototype unit that they made with four of our V3 dongles. By setting up several antennas connected to a multichannel coherent receiver calculations can be made to determine the direction a signal is coming from. Daniel Michał Kamiński in yesterdays post. Passive radar works by listening for strong signals bouncing off airborne objects such as planes and meteors, and performing calculations on the signals being received by two antennas connected to the multi-channel coherent receiver.Ī second example is direction finding experiments. Multimon daniel terhell software#Coincidentally, we’ve just seen the release of new GUI based Passive Radar software by Dr. One example application of a multi-channel coherent receiver is passive radar. More information on the registers and build of the receiver control board can be seen on their technical support page.Ī ten channel RTL-SDR coherent receiver. The I2C capability is useful because it means that several RTL-SDR dongles can be controlled and tuned from the same control signal. They also added an 8-bit register and I2C connection capabilities which allows for control of future add-on boards. In their receivers they attach a control board which has a buffered 0.1 PPM TCXO (buffered so it can power multiple RTL-SDR’s). The team at have used the new expansion headers on our V3 dongles to create their product. A multi-channel coherent receiver allows signal samples from two different antennas to be synchronized against time, allowing for all sorts of interesting applications such as passive radar and direction finding. An RTL-SDR multi-channel coherent receiver is at its most basic, two or more RTL-SDR dongles (multi-channel) that are running from a single clock source (coherent). ExtIO with Decimation & Tuner Bandwidth ControlsĪ Multi-Channel Coherent RTL-SDR Product: For Passive Radar, Direction Finding and MoreĬ is a company which is a customer of our RTL-SDR V3 dongle and they have been working on creating a multi-channel coherent receiver product based on the RTL-SDR.
