摘要： The present invention is a signal processing device that efficiently removes multiple types of interference waves mixed in with a received signal. This signal processing device is provided with: a first extraction unit that performs deconvolution with respect to a cross-correlation of a reference signal and a received signal and to an autocorrelation of the reference signal, and extracts a channel response to the reference signal; a second extraction unit that extracts a main channel response corresponding to the reference signal from the channel response; and a removal unit that restores a signal by performing convolution with respect to the reference signal and the main channel response, and removes the restored signal from the received signal.

摘要： A method for determining parameters of a finite impulse response pulse compression filter, implemented by a multi-channel radar comprises: a step Etp10 of transmitting a calibration signal and of acquiring this calibration signal after propagation through the transmission channel, a step Etp20 of injecting the signal acquired, at the input of each of the reception channels, a step Etp30 of measuring the signal at the output of each reception channel, a step Etp40 of calculating the transfer function of the matched filters on the basis of the signals at the output of the reception channels, a step Etp50 of measuring the value of the average power at the output of the various reception channels and of calculating the relative gains between each of the reception channels and a predetermined reception channel on the basis of the measured values of average powers.

摘要： A method includes receiving a signal, which includes reflections of multiple pulses from one or more targets (24). A Doppler focusing function, in which the reflections of the multiple pulses from each target accumulate in-phase to produce a respective peak associated with a respective delay and a respective Doppler frequency of the target, is evaluated based on the received signal. Respective delays and Doppler frequencies of the targets are estimated based on the Doppler focusing function.

摘要： Radio-frequency (RF) signal analysis includes slow-time signal processing and fast-time signal processing. Incoming RF pulses are captured according to a resource scheduling configuration. The fast-time signal processing is to prioritize the captured RF pulses for slow-time signal processing based on dynamic pulse-grading criteria. The slow-time signal processing is to perform relevance evaluation of the prioritized RF pulses, and to adjust the dynamic pulse-grading criteria and the resource scheduling configuration based on the relevance evaluation.

摘要： This document describes techniques and devices for type-agnostic radio frequency (RF) signal representations. These techniques and devices enable use of multiple different types of radar systems and fields through type-agnostic RF signal representations. By so doing, recognition and application-layer analysis can be independent of various radar parameters that differ between different radar systems and fields.

摘要： The technology described in this document can be embodied in a radar system that employs pulse compression waveforms. In one aspect, a radar system includes a transmitter device and a receiver device, which are both configured to access a storage device. The storage device is configured to store a first sequence of values and a second sequence of values. The first sequence of values can represent phase values for a transmit waveform. The second sequence of values can represent complex values for a filter waveform. The first and second sequences of values are generated via a joint optimization process. An objective function of the first and second sequences is a weighted sum of metrics indicative of a sidelobe level of a simulated range response and frequency suppression of the transmit and filter waveforms outside and portions inside of a target bandwidth.

摘要： There is provided an estimation device that estimates a living body orientation. The estimation device includes: transceivers that transmit transmission signals using M transmission antenna elements arranged to surround a predetermined range including a living body, and receive reception signals using N receiving antenna elements; and a circuit that, for each of M sets of N reception signals corresponding to transmitted M transmission signals, performs calculation of a characteristic quantity based on the N reception signals included in the set, the characteristic quantity with a greater value indicating a waveform having a larger amplitude and higher regularity, identifies a first transmission antenna element corresponding to a first characteristic quantity having a greatest value among M characteristic quantities by comparing the M characteristic quantities obtained by the calculation with each other, and estimates the living body orientation to indicate a predetermined direction based on the first transmission antenna element identified.

摘要： A system and method for qualitative analysis of time progressive signals, comprising: a qualitative signal analysis module, comprising at least a processor, a memory, and a long term storage device; and an output processor module comprising at least a processor a memory and a network interface has been devised. The qualitative signal analysis module retrieves signal data over time and applies pre-programmed protocols to compare multiple aspects of the signal data to derive meaningful data. The output processor module encodes data generated by the qualitative signal analysis module for use in subsequent analytical steps such as further manipulation, classification or long term storage.
