Abstract: In a method for determining a position of at least two sensors in relation to one another, a moving object is sensed by the at least two sensors, and at least one movement variable for the moving object is determined by one of the sensors, at least said movement variable or variables derived therefrom being used jointly for determining a position of the sensors in relation to one another. The sensor network is designed to carry out a method of said kind.

Abstract: Detection for localizing at least one particle moving in a flow includes emitting a transmission signal by a transmitter, and receiving a reflected reception signal. The reflected reception signal is frequency and phase modulated in comparison with the transmission signal. The reflected reception signal is convolved with at least one kernel representative of a conjugate estimated channel pulse response. A reconstructed particle position function is formed, and the position of the particle is determined from the reconstructed particle position function.

Abstract: A traffic monitoring system for a traffic area with parking surfaces for vehicles or a freely arrangeable row of vehicles includes overhead radar sensors oriented towards the area for capturing a chronological sequence of digital radar images thereof. An analyzing unit detects vehicles parked on the area and ascertains locations and dimensions thereof from the captured sequence and determines an occupancy state of the surfaces from a data comparison of the ascertained locations and dimensions of parked vehicles with configured geodata of surfaces. The parking surface is occupied or free for a vehicle, and a parking surface for a freely arrangeable row of vehicles is occupied or provided by one or more free parking spaces. An image output unit outputs a map view of the area with marked surfaces and the current occupancy state of the surfaces. The traffic monitoring system allows a more effective monitoring of the area.
