Future autonomous systems of cosmic ray radiodetection will be installed over large areas, encountering various environmental and noise conditions. It is thus essential to check and evaluate the influence of the vicinity on the sensitivity of detection. In this paper, the main environmental influences on the performances of the CODALEMA experiment are presented. It will be shown that the performances and sensitivity of the detector are not affected by the environment, and that the new CODALEMA autonomous detection station can reach the ultimate accessible sensitivity even in a quite noisy environment. This allows deconvolving the detector's response and recovering the real spectral characteristics of the cosmic ray air showers.
