There is provided a radar apparatus capable of extracting a peak signal obtained from a difference frequency between a transmitting signal and a receiving signal during first and second periods and deriving target information based on the extracted peak signals. A predicting unit derives a predicted peak signal obtained by predicting a current peak signal based on the peak signal obtained in a previous process.

Target position, movement and tracking system
The invention provides a target object detection system, comprising a plurality of sensing nodes (10) for positioning at respective detection locations with respect to a detection area (12) that is situated within a field generated by an ambient ac source of excitation. Each sensing node has at least one electric potential sensor (22, 42) designed to detect perturbations in said field caused by a target object (14), said one sensor including an electrode (20, 40) responsive to the ac excitation field for generating detection signals, an amplifier (28) connected to the electrode for receiving and amplifying the detection signals to produce ac measurement signals as output, and at least one feedback circuit (30, 36) from an output of the amplifier to an input thereof for enhancing the input impedance of the amplifier.
