The invention provides an X-band lunar explorer communication receiving and transmitting compatibility testing and analyzing method. A lunar explorer is complicated in task and is generally composed of a plurality of independent sub-explorers, and each sub-explorer is equipped with an independent measurement and control communication system which is used for independently communicating with the earth and carrying out communication demands among the sub-explorers, so a plurality of independent X-band communication receiving and transmitting channels (containing antennas) need to be arranged for the lunar explorer, and the communication receiving and transmitting channels work at different frequencies. An X-band range for deep space exploration allocated by the International Telecommunication Union is relatively narrow, intervals among the frequency points are very small, the size of the lunar explorer is small, and the intervals among the antennas mounted on the lunar explorer are small, so mutual interference is liable to cause among the communication receiving and transmitting channels. In order to determine the compatibility among the communication frequencies, the invention provides the X-band lunar explorer communication receiving and transmitting compatibility testing and analyzing method.
