Rydberg atom is an atom with a high principal quantum number. Its quantum coherence effect enables the measuring of radio frequency electric fields in space. In this work, the radio frequency pulse response characteristics of the radio frequency receiving system based on the Rydberg atom under different pulse widths and intensities are studied. In the experiment, lasers with wavelengths of 852 nm and 510 nm are used to excite cesium atoms. Moreover, a radio frequency source emits pulse signals with different parameters to irradiate Rydberg atoms. The probe signal transmitted from the atomic vapor cell is directed at the photodetector. Moreover, the oscilloscope records the electrical signal obtained by photoelectric conversion. In addition, the simulation ranging is performed by setting different pulse delay times through the fiber delay instrument. It preliminarily proves that the radio frequency receiving system based on Rydberg atoms has a function of pulse ranging.
