24GHz Microwave Radar Sensor

Hi, I'm on a senior design project building an FMCW radar. We are looking at using the 24GHz microwave sensor, sold by dfrobot, as a reference design that we can compare our work to at the end of the project. In order to do this, I need access to the datasheets for the parts used on this board. Does anyone know what parts are used on this design -- I've noticed the ST Micro, but cant make out markings on the other two ICs.
