We have extended our motion detection by contactless multi-channel UWB radar for cardiac MRI navigator to a 4x8 channel system to make the application more robust. The new system is insensitive to a not well placed antenna configuration related to the position of the monitored person. Additionally a method for rejecting noisy channels was implemented to avoid average effects.
