“…Based on full duplex transmission, offsets and phase information of the down-converted intermediate frequency (IF) signals are highly correlated and unknown parameters can be deduced from the analog-todigital converter (ADC) data [26], [27]. The suppression of correlated PN using the dual-ramp (DR) FMCW enables a ranging standard deviation below 1 cm for distances up to 1 km [28]. Synthetic coherence of the carrier phase can also be established by correction of the unknown initial phases [29], [30].…”

“…Another group of secondary radar uses parallel data link for synchronization of two widely equal equipped units. This usually requires a separate transmission channel (Feger et al, 2012;Schreiblhofer et al, 2014). In the concept of synchronized units, each unit is equipped with an own oscillator that is clocked independently, giving reason for additional effort on synchronization (Roehr et al, 2008;Stelzer et al, 2008).…”

Abstract. The increasing availability of off-the-shelf high-frequency components makes radar measurement become popular in mainstream industrial applications. We present a cooperative FM radar for strongly reflective environments, being devised for a range of up to approx. 120 m. The target is designed with an unambiguous signature method and satisfies coherence. A prototype is built with commercial semiconductor components that operates in the 24 GHz industrial, scientific and medical band. First experimental results taken in sewage pipes are presented, using the target prototype and a standard FMCW radio station. An overview on four data acquisition procedures is given.

We present the implementation of a cooperative radar system on a gantry rail crane for distance measurements in an industrial environment. The measurement approach is based on the dual-ramp frequency-modulated continuous-wave principle, using identical sensor-nodes at the endpoints of the range of interest. Pseudo-range information is exchanged via a dedicated data-link between these stations. At the sensor-node a flexible high-performance signal processing and remote management engine is implemented. The system setup is controlled by a single host-PC, which is used as a man–machine interface for configuration of the remotely controlled measurement stations, system surveillance, and visualization of the measurement data. Indoor characterization of the developed hardware is sufficient for an efficient calibration of the system, minimizing distance offsets. On-site measurements at distances up to 1000 m with an accuracy better than 2 cm confirm the performance of the ranging system. Furthermore, the results are verified by simulation.
