摘要： The invention relates to a measuring device for electromagnetic waves, in particular a radar apparatus, for a measurement of a measure, in particular a distance, in particular a distance of one or more objects to be measured, and/or a signal intensity, in particular a signal intensity correlating with a size and/or quantity of one or more objects to be measured, with compensation of a drift behavior, in particular a temperature-dependent drift behavior, comprising a housing, in particular a hermetically sealed off and/or lockable housing, a sensor and/or receiver for electromagnetic waves which is/are which is/are arranged in the housing, in particular a receiver for electromagnetic waves in the radio frequency range, which comprises, in particular, an oscillator, a detection device, which is arranged in the housing, for detecting at least one physical parameter, in particular a physical parameter of the environment, in particular a temperature, in particular an ambient temperature, in particular a temperature of an ambient air in the housing, and/or a current oscillation frequency and/or natural frequency of an oscillator, in particular an oscillator, frequency generator and/or oscillation crystal of the sensor or receiver.
The invention further relates to a method for measuring a measure, in particular a distance, in particular a distance of one or more objects to be measured, and/or a signal intensity, in particular a signal intensity correlating with a size and/or quantity of one or more objects to be measured, with compensation of a drift behavior, in particular a temperature-dependent drift behavior, in particular using a measuring device for electromagnetic waves, further in particular a radar apparatus, at least comprising the following steps:



a detection of at least one physical parameter in a housing, in particular a hermetically sealed and/or lockable housing, in which a sensor and/or receiver for electromagnetic waves is arranged, wherein the at least one physical parameter comprises a physical parameter of the environment, in particular a temperature, in particular an ambient temperature, in particular a temperature of an ambient air in the housing, and/or a current oscillation frequency and/or natural frequency of an oscillator, in particular an oscillator of the sensor or receiver for electromagnetic waves;
obtaining, in particular calculating or reading from a database, a compensation and/or compensation function and/or a compensation factor on the basis of the at least one physical parameter, in particular a compensation and/or compensation function, which is suitable for compensating, on the basis of the at least one physical parameter, a measuring error caused by an environmental parameter and/or an environmental factor on a measurement result which is based at least in part on a sensor and/or receiver for electromagnetic waves.
