Investigation of CW and LFM waveforms for Bi- and Multistatic Radar Synchronisation

Multistatic radar systems have long been of great interest to a wide range of applications. Due to the uncoupled local oscillators in each radar, synchronisation of the radars is necessary to perform coherent processing of the data. Considering the use of synchronisation signals independent from the signals used for the radar operation, this paper analyses the estimation performance of Continuous Wave (CW) and Linear Frequency Modulated (LFM) waveforms when their parameters such as bandwidth, frequency, and duration are varied. Effects of synchronisation errors are shown for Synthetic Aperture Radar (SAR) imaging, however the synchronisation concepts are not exclusive to SAR.
