24-GHz radar movement detector kit

November 27, 2017 // By Julien Happich
Aspen Electronics is now stocking the K-LD2 evaluation kit from RFbeam Microwave for use in movement detection and speed measurement.

The K-LD2 is a fully operational 24-GHz radar movement detector. It combines a K-LD2 24-GHz digital and low-cost radar movement detector module with a DSP chip, providing users with a more complete system than just the radar module. This will allow those interested in “radar motion sensing” to make better use of the technology as this offering represents a much simpler approach when compared to the prospect of using a radar module and developing your own signal processing algorithms.  

The K-LD2 sensor comes with a 2 x 4 patch antenna radar front-end with an asymmetrical beam and a powerful signal processing unit with two digital outputs for signal detection information. The evaluation board visualises the two digital outputs of the K-LD2 using two LEDs. The sensitivity and the hold time are adjustable using analogue inputs with potentiometers. The serial interface features a command set to read-out advanced detection data or to fully customise the detection algorithm. The digital structure makes it very easy to use in any stand-alone or MCU based application where a movement detection or speed measurement is required.

Also included is control panel software where all the parameters can be modified to help drastically reduce development time.
