To solve the problem that the receiving equipment was generally expensive and the integration was not high enough， a four‑channel ADS‑B receiver based on low cost and high integration was designed.This device was the first four‑channel small RF receiving device in the industry that integrated low‑cost real‑time signal acquisition， on‑board multi‑band ADS‑B real‑time decoding and other functions.The equipment was based on ZYNQ‑7000 series chip as the main control chip. The design included RF front‑end receiving circuit module， signal acquisition circuit module， high‑speed and large‑capacity data storage module， etc.， which realized high‑speed sampling and processing of target signals， such as ADS‑B.The test results showed that the receiver could successfully receive and demodulate ADS‑B long message signals， providing a set of low cost and low power overall solution for high performance data acquisition and real‑time signal processing.
