Abstract

一种提高雷达系统激光测距能力的方法、装置及存储介质，该方法包括：通过获取激光器的当前工作温度、激光器的预设工作温度范围、以及激光器的中心波长温度变化率(S301)；基于激光器的预设工作温度范围和激光器的中心波长温度变化率，确定光学滤波片的带宽，并基于光学滤波片的带宽建立雷达系统(S302)；基于激光器的当前工作温度确定激光器的当前中心波长(S303)；在激光器的当前工作温度小于预设工作温度范围的最小临界值的情况下，加热激光器直到激光器的当前工作温度至少达到预设工作温度范围的最小临界值(S304)。本方法可以通过维持激光器的工作温度的方式，减少入射到雷达系统的环境光等光噪声，从而提高雷达系统的抗干扰能力和测距能力。
