Herein disclosed is a method for radar detection of a valid target within a monitored zone with disturbing elements passing therethrough, e.g. process scraps of a machine on which the radar system is installed. The method includes transmitting, receiving and processing radar signals to locate and track the movement of a moving potential target. The method discriminates whether the potential target is valid or not, by checking whether the potential target has an initial position within a disturbance zone and whether it is detected for an overall detection time period that is less than the assessment time interval. If a target is not valid, it will be assimilated to background after it stops.

Radar detection in environments with disturbing elements

A method of estimating a radar cross section of a target in an environment using a detection device, wherein the detection device is configured to transmit transmission signals into a field of view and to receive reception signals, may include: generating a calibration curve that provides signal amplitude values as a function of positions in the field of view; detecting a reception signal, obtaining a corresponding detection profile, and analyzing the detection profile to identify the target, having a target signal amplitude and a target position corresponding thereto; and estimating the radar cross section of the target by comparing the target signal amplitude with a signal amplitude base value, provided by the calibration curve at the target position. The generating of the calibration curve may include: generating a combined profile as a function of position; and optionally, generating a filtered profile by applying a filter to the combined profile.

Methods of detecting targets with environment-adaptive calibration

A method of detecting objects in an environment using coexisting radar devices is disclosed. According to the method, the transmission intervals of the devices are spaced apart by a wait time given by the sum of a base time, common to all the radar devices, and respective time delays, differing between devices and shorter than the base time. For each pair of devices the difference between the time delays is less than the transmission time but is at least twice a risk time in which a collision between the signals of different radar devices can be confused for an object to be detected. Given a sequence of detection cycles, a radar device is determined to have detected a target if the result of the detection is positive for a number of consecutive detections which is at least equal to the number of radar devices.

Systems for detecting objects in environments

Disclosed is a method for detecting tampering of a target detection system, comprising a control unit is in signal communication with a set of present tamper detection sensors, which are associated with a detection member. The method includes setting an overall sensor coordination logic for determining a tamper state of the system based on tamper detection data from a predetermined set of sensors, wherein the set of present sensors is a subset. Then, the control unit controls the operating state of each sensor of the set of present sensors and defines a reduced sensor coordination logic, excluding those sensors of the predetermined set that are missing and/or non-working from the overall logic. Thus, the present and working sensors cyclically acquire tamper detection data, and the control unit determines the tamper state of the system by processing the data acquired based on the reduced logic.

Methods for detecting tampering of target detection systems

A method for detecting motion may include: performing at least one scanning cycle on a monitored space using a radar apparatus; detecting and identifying at least one moving object in the monitored space, including detecting an actual displacement value for each moving object detected inside the monitored space between a detection cycle and a subsequent detection cycle; providing a threshold value of maximum allowable displacement associated with every moving object detected inside the monitored space between the detection cycle and the subsequent detection cycle; locating at least one semi-static zone in the monitored space, the at least one semi-static zone corresponding to a portion of the monitored space that surrounds at least one semi-static object; and generating an alarm signal only when, in the monitored space, at least one moving object situated outside the at least one semi-static zone is detected.
