Claim:
1. A system for detecting object movement comprising: a sensory network having at least one sensory device using modulated radar for detecting an object in proximity to the sensory network, the sensory network including wireless transmission means and a Doppler radar transceiver coupled to an inverting amplifier which couples to a wireless mote sensor; and a base station having computer processing means located remote from the sensory network and including wireless transmission means to communicate with the sensory network, the base station having computer readable program code means for causing the computer processing means to analyze data received from the sensory network including data obtained by the Doppler radar transceiver to determine motion characteristics of the object in proximity to the sensory network, the motion characteristics including at least a range of distance between the object and the sensory network, wherein the inverting amplifier receives an output signal directly from the Doppler radar transceiver, inverts the received output signal, and transmits the inverted output signal directly to the wireless mote sensor, the inverted output signal is received at the wireless mote sensor via an Analog-to-Digital Converter (ADC) provided on the wireless mote sensor, and a microcontroller provided on the wireless mote sensor processes the inverted output signal received at the wireless mote sensor to form a decision support system supporting the motion characteristics determined by the base station.
