There is provided an information processing device, a mobile terminal, and an information processing method capable of executing information processing more reliably. Bluetooth Low Energy (BLE) is used to transmit a beacon that is a signal for detecting a mobile terminal within a communication range of the BLE. Ultra Wide Band (UWB) is used to perform ranging processing of measuring at least a distance from the mobile terminal detected using the beacon to a UWB gate unit provided with a fare calculation zone in which fare payment processing is performed with the mobile terminal. Then, when it is detected that the mobile terminal enters the fare calculation zone on the basis of a result of the ranging processing using UWB, data communication for payment using UWB is performed between the UWB gate unit and the mobile terminal. The present technology can be applied to, for example, a touchless fare payment system using BLE and UWB.

A radar sensor for sensing the level of a product or the topology of the surface of a product having a continuously operated clock that closes a power supply line to the processor at a predetermined time to activate the processor. Thereupon, the processor controls the switching arrangement to activate the radar chip.

A system for locating a RFID tag in a space or area having a physical barrier is disclosed herein. More specifically, the system comprises a plurality of guard tags for use in conjunction with a RFID tag disposed on an item and a RFID reader for locating the same. The system is configured to locate the RFID tag on either side of the physical barrier. The plurality of guard tags may comprise a plurality of negative encoded guard tags and a plurality of positive encoded guard tags, and an algorithm may be used to determine a probability of the RFID tag location within the physical space. A method of locating a RFID tag within a physical space, and a method of virtually shielding the physical space is also disclosed.

Methods and systems are disclosed for determining a spatial position of an aircraft, without replying on measurements from the Global Positioning System. Various embodiments are described using a single Secondary Surveillance Radar (SSR), and multiple SSRs.

Embodiments described herein are concerned with system for identifying an aerial vehicle. The system comprises: a radar sub-system, the radar sub-system comprising at least one radar connectable to a static support member and a transceiver configured to transmit data indicative of one or more targets identified by the radar within an airspace; a receiver arranged to receive the data indicative of one or more targets identified by the radar; and a processing system configured to process said data, whereby to identify at least one aerial vehicle. In some embodiments the radar comprises a marine radar.

A radar signal processing device includes: a frequency analysis unit performing frequency analysis on a reception signal of at least one reception channel generated by a sensor unit; a target object discriminating unit calculating, on the basis of the frequency analysis, a measurement value of at least one type of feature amounts that characterizes a state of a target object moving in an observation space; and a learned data storing unit storing at least one learned data set that defines a probability distribution in which the at least one types of feature amounts is measured when a recognition targets is observed in the observation space. The target object discriminating unit calculates a posterior probability that a target object belongs to each of class(es) from the measurement value using a learned data set and discriminates the target object on the basis of the calculated posterior probability.

An adaptive interrogation method is provided, the method including determining application of an adaptive whisper shout interrogation sequence. The determination may be predictive and based on an anticipation of garbled replies or may be reactive and based on a plurality of replies to an initial ATCRBS interrogation, there being interference between the replies such that the replies are unable to be properly decoded. The adaptive whisper shout interrogation sequence includes adapting a subsequent ATCRBS interrogation. The adaptation may be a change in an amplitude difference between an interrogation pulse and a suppression pulse of the subsequent ATCRBS interrogation (i.e. a bin width), as compared to the initial ATCRBS interrogation; or the adaptation may be a change in a power of the subsequent ATCRBS interrogation as compared to the initial ATCRBS interrogation. The subsequent ATCRBS interrogation is then transmitted, and one or more replies are received.
