Abstract: The learning device learns a tracking model used for a radar device. A first acquisition unit acquires, from a radar device, a target detection information indicating a position of a target detected based on a received wave, and a track of the target calculated based on the target detection information. A second acquisition unit acquires a target position information indicating a position of the target. A learning data generation unit generates learning data using the target detection information, the track, and the target position information. A learning processing unit learns a tracking model for performing tracking processing of the target based on the target detection information, using the learning data.

Abstract: The present invention relates to a signal processing device for accurately detecting a moving object without being influenced by the speed of the moving object. This signal processing device is provided with: at least two cross-correlation calculation units for calculating cross-correlation functions for the waveform of a reflection signal obtained through the reflection, by an object, of a transmission signal having a varying frequency and different correlation waveforms generated from the waveform of the transmission signal; a combination unit for combining the at least two cross-correlation functions from the at least two cross-correlation calculation units so as not to be separated in the frequency shift direction; and a detection unit for detecting the object on the basis of the cross-correlation function resulting from the combination.

Abstract: A wireless network relay apparatus includes a Layer 2 switch and a line control device as well as wireless/wired line terminating devices performing band limitation associated with an AMR function. It measures traffic passing through each line terminating device in inflow/outflow path directions. Upon detecting a modulation scheme changed due to an AMR function in a wireless area, it may specify a line terminating device so as to read a desired modulation scheme from a transmission source modulation scheme conversion table of the line control device based on traffic. It may change a local modulation scheme with a desired modulation scheme when a difference therebetween is above a predetermined number of stages. By tracking a modulation scheme changed for a transmission destination, it is possible to appropriately change a modulation scheme for a transmission source, thus suppressing traffic without discarding necessary data.
