测距误差按其性质可分为随机误差和系统误差，其中系统误差是在测距时系统各

Ranging error can be divided into random error and system error according to its nature. System error is the error caused by the delay of each part of the system during ranging. In theory, the system error can be compensated by calibrating the radar But it is difficult to compensate in actual work, so the allowable system error range is often given during the ranging process

Range-testing error can be divided into random error sandals and system errors by its nature, wherein the system error is the error caused by the delay of the signal in various parts of the system during range testing, theoretically, the system error can be compensated by calibrating the radar, but because it is difficult to compensate for the actual work, so the allowed system error range is often given in the range testing process.
