The hardware is designed as a modular system with 4 layers:
Layer 1 and core component is a base board with microcontroller that includes baseband processing, AD conversion and output to USB and other interfaces. The power supply via USB also takes place here.
Layer 2 are the radar front end boards which are plugged onto this base board – one at a time. These are available in different versions that include different radar chips. Usually the radar front end boards also include the antennas, depending on the version in the radar chip or as a patch antenna on the board.
Layer 3 are beam shaping elements (lenses or reflectors) which come with some boards. They can be used to narrow the beam and increase range.
Layer 4 is the optional break out board. It offers extended connection options, e.g. to 2 x 15 pin headers of 2.54 mm each.
All modules of the SiRad Easy® r4 can be purchased separately. In addition, we offer two bundles (see “Scope of Delivery”).
