Abstract: Target monitoring and alert systems for identifying and tracking targets within radar data. Raw frame data is filtered to remove data relating to reflections from static objects. Moving targets are identified in the filtered data and their location is tracked over time generating target data. Neural networks may process the target data, calculate a fall likelihood score and generate a fall-alert if this is above an alert-threshold. A person identification module may extract the position and motion characteristics of each target from the data and generate a probabilistic identification of the target with a person.

Abstract: Systems and methods for identifying and/or measuring displacement of at least one sensor in system comprising at least two sensors, each sensor comprising a signal generator wherein the signal produced by the generator is used as a transmitted signal and as a local oscillator for down converting signals received from other sensors to produce an IF (intermediate frequency) signal; a data acquisition subsystem configured to generate data samples comprising phase information of the plurality of IF signals and record said data samples; at least one processor, said at least one processor is configured to: receive the recorded data samples from each sensor of said at least two sensors; jointly process the recorded data samples from each sensor of said at least two sensors to extract a phase value which depends on the distance between the at least two sensors; measure over time said phase value to yield a phase change value; identify displacement of at least one sensor of the at least two sensors based on the extracted phase change value.

Abstract: Systems and methods for scanning concealed surface and detecting concealed objects using a radar. A radar-based sensor unit has an array of transmitters and receivers which transmit a beam of electromagnetic radiations towards a subject being scanned and receive the reflected electromagnetic signals. A processing unit receives raw complex image data from the radar unit and processes the data for detecting specific concealed objects. A display unit displays images representing the concealed object. A database stores the processed data from the processing unit along with the raw complex image and the processed image data. Stored data may be used to train the processing unit for accurately detecting the specific concealed objects. A communicator may transmit notifications through a communication network.
