A fixed-receiver mobile-transmitter passive bistatic synthetic aperture radar (MF-PB-SAR) system, which uses the Sentinel-1 SAR satellite as its non-cooperative emitting source, has been developed by using embedded software-defined radio (SDR) hardware for high-resolution imaging of the targets in...
Those spoofing scenarios using the open-source software-defined GPS simulator such as ‘gps-sdr-sim’ ((https://github.com/osqzss/gps-sdr-sim): Software-Defined GPS Signal Simulator that generates GPS baseband signal data streams, which can be converted to RF using SDR platforms, such as ...
Usage: gps-sdr-sim [options] Options: -e <gps_nav> RINEX navigation file for GPS ephemerides (required) -q <gps_nav> RINEX navigation file for QZSS ephemerides (any) -u <user_motion> User motion file in ECEF x, y, z format (dynamic mode) -x <user_motion> User motion file in ...

These are signals that have are active or have been active within the last 6-12 months. You have a very good chance of finding any one of these out on the airwaves. Click the name of a signal to see more detailed information, possible decoding, and additional sound and waterfall samples...
The "real world" analog input signal, typically from a microphone or line-level source The A/D converter word size and conversion errors DSP finite word length effects such as quantization errors resulting from truncation and rounding, and filter coefficient quantization ...
One commonly overlooked source is the DC power solution, which can couple to and severely degrade the performance of the signal chain. Our results show that proper choice of power modules is paramount and can lead to as much as a 10 dB improvement of phase noise at 10 kHz offset. For ...
For SDR and Test Equipment applications, be sure your RF-in is well-calibrated. Service: Bree at Shenzhen Zd Tech was very helpful with the process of ordering the just-the-amps with the connectors I needed. Good transparent communications with the tech staff about the production and test ...
However, this oversampling imposes unnecessary complexity on the acquisition stage of the GNSS receivers where an approximate estimate of the code phase and Doppler frequency shift is produced. Therefore, reducing the sampling frequency for the acquisition stage reduces the overall receiver complexity ...
