Embodiment Construction
[0056] Such as figure 1 Shown is a flowchart of an adaptive radio frequency interference cancellation method for radio astronomy signals according to an embodiment of the present invention. The adaptive radio frequency interference elimination method of the present invention is applicable to various radio astronomy signals, and in this embodiment, the radio astronomy signals are pulsar signals.
[0057] Such as figure 1 As shown, the adaptive radio frequency interference elimination method of the radio astronomy signal specifically includes the following steps:
[0058] Step S1: Obtain baseband data, which includes reference data and observation data.
[0059] Wherein, the baseband data is acquired by an adaptive interference elimination system, and the adaptive interference elimination system includes a reference antenna system (that is, a reference system) and a radio telescope (that is, an observation system). In practical applications, the observation The data are obtai...
