The IMST 24 GHz FMCW Radar Development Kit DK-sR-1800e consists of 1 transmit and 8 receive antennas. The transmit antenna covers 70° in azimuth and 8° in elevation. The 8 receive channels cover fixed sectors of 9° beam-width in azimuth and 8° in elevation, so that unambiguous distances and velocity can be measured in each sector. This is achieved by applying a Rotman Lens in the frontend circuit. DK-sR-1800e comes with a Graphical User Interface (GUI) called SenTool. SenTool makes it easy to configure the sensor and to measure, visualize and analyze the data of the radar in several different graphical plots.
