The system improves the resolution by dynamically varying the effective range of a sensor and aggregating the supersonic signal reflected from the object. Sensor contains several lattice converters(10) and they receive supersonic signal cluster reflected from the object. Amplifiers(AMP1~AMPk) amplifies the output signal from the lattice converters. Lattice converters(10) varies the effective range of the sensor by the depths of the reflected supersonic signal cluster. Sampling switches(SW1~SWn) performs sampling from the amplified signal cluster and the samples are stored in buffers(BUF1~BUFn). Selection switches(SW1`~SWn`) selectively transmit the output signal from the buffer. Adding device(20) adds the signals from the selection switches and generates the aggregated signal.
