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 system and a Doppler radar transceiver coupled to an active filter arrangement which couples to a mote sensor; and a base station having a computer processing system located remote from the sensory network and including a wireless transmission system to communicate with the sensory network, the base station having a computer readable program code for causing the computer processing system 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, wherein the active filter arrangement includes first, second, and third active filter elements, the first active filter elements couples to a first Analog-to-Digital Converter (ADC) provided on the mote sensor, the second active filter element couples to a second ADC provided on the mote sensor, and the third active filter element couples to a Digital-to-Analog Converter provided on the mote sensor.
