摘要： The invention relates to a method for operating a radar system. Radar systems are used for determing the distance of at least one reflecting object in an observation area and/or the speed of the at least one reflecting object. Said type of radar system emits successive pulses corresponding to a predetermined pulse duration with a specific pulse repetition frequency as emission signals in the observation area and receives the emission pulses of the emission signal reflected on the at least one reflecting object as a receiving signal. The disadvantage of such a method is that it involves a high signal dynamics, which has a negative effect on the price of circuit parts required for signal processing. The novel method for working the radar system should be developed via an economic means. According to the novel method the signal dynamics are reduced by predetermining the average output of the emission signal and by reducing the average output of the emission signal by variation, preferably by varying the pulse repetition frequency and/or the pulse duration of the emission pulse to the specific output range. The method is particularly suitable for operating a distance warning system for a motor vehicle.

摘要： A radar system includes a transmit front end device including a transmit planar component, and a receive front end device including a receive planar component. Each of the transmit planar component and the receive planar component includes a first end, a second end, a cavity space and a linear array of antennas. The cavity space is bounded by beam ports along a first side of the cavity space and by array ports along a second side of the cavity space. The cavity space is in operative communication with the beam ports and with the array ports to form a Rotman lens. A linear array of antennas is located along the second end of the planar component. The transmit planar component and receive planar component are arranged such that the linear array of antennas of the transmit planar component and the linear array of antennas are perpendicular to one another.

摘要： Methods and systems for remote sleep monitoring are provided. Such methods and systems provide non-contact sleep monitoring via remote sensing or radar sensors. In this regard, when processing backscattered radar signals from a sleeping subject on a normal mattress, a breathing motion magnification effect is observed from mattress surface displacement due to human respiratory activity. This undesirable motion artifact causes existing approaches for accurate heart-rate estimation to fail. Embodiments of the present disclosure use a novel active motion suppression technique to deal with this problem by intelligently selecting a slow-time series from multiple ranges and examining a corresponding phase difference. This approach facilitates improved sleep monitoring, where one or more subjects can be remotely monitored during an evaluation period (which corresponds to an expected sleep cycle).

The preferred embodiment of the proposed Smart-Sensor System is comprised of (1) a low-cost, non-coherent radar, whose function is to detect and track people, singly or in groups, and various means of transportation, which may include vehicles, animals, or aircraft, singly or in groups, and cue (2) an optical sensor such as a long-wave infrared (LWIR) sensor, whose function is to classify the identified targets and produce movie clips for operator validation and use, and (3) an IBM CELL supercomputer to process the collected data in real-time. The Smart Sensor System can be implemented in a tower-based or a mobile-based, or combination system architecture. The radar can also be operated as a stand-alone system.
