A Sonar Sensor with Random Double Pulse Coding
نویسندگان
چکیده
Double pulse coding is used to give sonar sensors a distinctive 'voice', allowing several to operate concurrently in the same acoustic space. This paper describes the use of random spacing between the two pulses to overcome interference problems arising when the same spacing.occurs between targets or ··is used by another •·•··•.. sensor. Results demonstrate the robustness ·of this method in comparison with previous approaches. The echoes are digitised by a ·1 MHz, 12 bit ADC and processed on a custom DSP system.

متن کاملFast target classification using sonar
This paper describes a new sonar system that can perform target localisation in two dimensions and classification into planes, concave corners and convex edges with no extra time overhead. That is, the sensor transmits on two transmitters a short time apart, thereby collecting echoes in virtually the same time as a single transmitter system. Moreover, the time separation of the transmitted puls...
متن کاملFast and accurate sonar trackers using double pulse coding
A new sonar target tracking system is presented that is capable of accurately tracking targets at measurement rates exceeding 10 Hz. Two sonar trackers, each consisting of a transmitter and two receivers, are independently controlled to track sonar targets from bearing and range measurements. Bearing and range are accurately estimated using matched filters on two closely spaced receivers, with ...
متن کاملSensor design and signal processing for an advanced sonar ring
A conventional sonar ring measures the range to objects based on the first echo and is widely used in indoor mobile robots. In contrast, advanced sonar sensing can produce accurate range and bearing (incidence angle) measurements to multiple targets using multiple receivers and multiple echoes per each receiver at the expense of intensive computation. This paper presents an advanced sonar ring ...
