The invention provides an irregular observation system design method and device, and belongs to the technical field of geophysical exploration. According to the technical scheme provided by the embodiment of the invention, the simulation data can be obtained based on the constructed complete simulation observation system and the geological information of the to-be-observed block. Based on a preset reconstruction technology, a corresponding target processing domain is obtained, so that a better reconstruction effect can be obtained, and based on the analog data, a preset under-sampling rate and a preset under-sampling mode, under-sampling processing is performed on each gather in the target processing domain in sequence, so that a better reconstruction effect is obtained. According to the method, the shot point position and the detection point position which are not sampled are deleted from the simulation observation system, so that the irregular observation system is obtained, the signal-to-noise ratio of dat
