Low-power X-band radar for indoor burglar alarms

Design and realization of a hybrid microwave integrated circuit (HMIC) for a low-power X-band Doppler effect radar system is presented. The radar operates within the range 9.9-10.5 GHz. The system is able to detect the frequency shift between the transmitted and the target reflected signal, providing an IF signal output that can be used for different types of post-processing. The design of the different units composing the system is detailed. Application of this system to indoor intrusion alarms is also fully described.<
