Summary In this paper, we design a high‐sensitivity noncoherent receiver for the reception of automatic dependent surveillance‐broadcast (ADS‐B) signals in a satellite‐based application. The proposed receiver is of constant false alarm rate (CFAR) property and implemented completely by the field programmable gate array (FPGA). Two vital parameters of the receiver, probabilities of detection and correct reception, are analytically formulated and validated by Monte Carlo simulations as well. We examine the availability of algorithms exploited in the proposed receiver by feeding the real ADS‐B signals collected near the Nanjing Lukou International Airport. Then, we build a receiver prototype. Some prototype tests are carried out in the laboratory. We find out that the sensitivity of the proposed receiver is approximately − 98 dBm, corresponding to the probability of correct reception equal to 0.93, and it is consistent with the theoretical value.
