Temperature compensation method, power detection device and radar system

Abstract

The embodiment of the invention provides a temperature compensation method, a power detection device and a radar system. The temperature compensation method comprises steps: the ambient temperature measured by a temperature sensor is compared with a preset temperature range; if the ambient temperature is located out of the preset temperature range, based on a temperature compensation curve, the ambient temperature is compensated, and compensated temperature is thus obtained, wherein the temperature compensation curve is generated based on a least square method. according to the temperature compensation method provided by the embodiment of the invention, the real ambient temperature can be obtained by directly compensating the ambient temperature measured by the temperature sensor through the temperature compensation curve, and the operation is simple, convenient and quick; and besides, as the temperature compensation curve is generated based on experimental data and the least square method, the reliability of the curve is high, and the compensation effects are enhanced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of power detection, and in particular to a temperature compensation method, a power detection device and a radar system. Background technique [0002] A temperature sensor refers to a sensor that can sense temperature and convert it into an available output signal. Since there is a certain correspondence between the available output signal and temperature, the corresponding temperature can be obtained through the available output signal. Therefore, the temperature sensor is usually used to detect ambient temperature. However, due to the widespread measurement error of the currently used temperature sensors, that is, there is an error between the detected ambient temperature and the real ambient temperature, and the higher the real ambient temperature, the lower the detected ambient temperature. The reason for this phenomenon is that the zero point of the temperature sensor drifts due t...
