The radar altimeter prelaunch calibration was commonly carried our by return signal simulator. The principles of return signal simulator, biases such as quadratic phase bias, amplitude and phase biases, delay bias were described in detail in this paper. In the last section the overall system bias on return signal simulator was calculated.
