Pilot frequency phase coincidence fuzzy region characteristic pulse detection system and detection method

The invention discloses a pilot frequency phase coincidence fuzzy region characteristic pulse detection system which comprises an FPGA module, a fuzzy region pulse generation circuit, a first difference vernier delayer, an XOR gate circuit module, a second difference vernier delayer, a third difference vernier delayer, a NOT gate circuit module and an AND gate circuit module, which are connected in sequence. The fuzzy region pulse generation circuit is directly connected with the XOR gate circuit module; and the second difference vernier delayer is directly connected with the AND gate circuit module. The detection system and detection method can realize pilot frequency phase coincidence fuzzy region characteristic pulse detection effectively, and has the advantages of high precision and high reliability.
