“…The acquisition system is composed of two software defined radio (SDR) platforms based on Ettus USRP E312 (Emitter) and B200 (Receiver) boards, linked to a laptop to record the data. As in [33], this setup was chosen because it allows quick development and experimentation tasks on RFs from 70 MHz to 6 GHz, it is quite cheap and is available off‐the‐shelf. Radar waveforms, emitted by the URSP E312 board, are generated from bin files coded from a database gathering more than 40 typical radar waveforms with agile (random variation)/hopping (systematic variation) frequencies and jittered/staggered PRI.…”

“…The two platforms work independently, there is no wire connection between them, so a clock on each platform and a mean of synchronization are required in order to measure TDOA. The chosen clocks are Temperature Compensated X (crystal) Oscillators (TCXO) because they have good short-term stability properties [6]. Synchronization is achieved by emitting a signal from platform 1 (see section III).…”

In this paper is described an experimental passive localization system based on SDR (Software Defined Radio) components. This system is designed to measure Time Differences of Arrival (TDOA) of radar pulses between two platforms. For a TDOA system, time error between the two receivers must be kept very low, which requires a very accurate way to synchronize the time bases. In this purpose, a custom offline synchronization method is proposed. The overall performances of the system are analyzed. In a small scale outdoor experiment, it has been shown to perform TDOA measurements accurately. The performances measured during this experiment are then extrapolated to a more realistic electronic warfare scenario.
