Asynchronous Compressive Multi-Channel Radar for Interference-Robust Vehicle Collision Avoidance Systems Conference Paper uri icon

abstract

  • © 2014 IEEE. This paper presents a low-power asynchronous compressive sensing (ACS) front-end scheme that allows the coexistence of radar and wireless systems. The analog front-end architecture introduces one major system advantage needed in an interference-robust wideband radar: multiple parallel signal processing channels capable of rejecting inband interference and handling large data volume at the analog-to-digital converters output. This advantage is offered by a filter-bank parallel ACS receiver that filters out undesired interference and exploits the sparsity of radar pulsed signals in a scattered environment. Numerical simulations on a vehicle-to-vehicle collision avoidance radar system with in-band wireless interference demonstrate the proposed radar receiver is robust to in-band interference, and achieves 6-fold data volume compression compared with Nyquist sampling.
