A pulse radar ranging apparatus and a ranging algorithm thereof are provided. The pulse radar ranging apparatus includes a radio frequency pulse generator, a radio frequency filter, a radio frequency switch and a transceiver aerial. The radio frequency pulse generator generates a pulse signal. The radio frequency filter receives the pulse signal and generates a high-pass filter signal, wherein the high-pass filter signal includes a radio frequency pulse reference signal. The radio frequency switch controls an output of the radio frequency pulse reference signal. The transceiver aerial transmits the radio frequency pulse reference signal. The radio frequency pulse reference signal contacts an object and generates a return signal, and the transceiver aerial receives the return signal. The ranging algorithm processes and analyzes the signals obtained by the pulse radar ranging apparatus, and calculates a distance between pulse radar ranging apparatus and the object by using polynomial interpolation.

A symbol rate testing method based on signal waveform analysis is provided. A signal with a plurality of quasi bitsand a plurality of quasi bitsis received and sampled within an acquiring time. Maximum values of the quasi bitsare obtained by calculating sampling values of the signal at various sampling points. A minimum value among the maximum values is determined as a critical value. Whether a quasi bitis a bitor not is determined according to the critical value, and a total number of the bitswithin the acquiring time is counted. Similarly, a number of the bitswithin the acquiring time are also obtained. Thus, the symbol rate is obtained according to the above information.
