- Non-coherent energy detection was the key technique of frequency-shift keying modulation, so the system introduced Chirp signal as the carrier signal for its performance with sharp energy peak, easy to detect and judge to reduce the probability of error.
非相干能量检测是频移键控技术的关键，系统采用线性调频信号作为载波信号，其匹配信号具有尖锐的能量峰值，易于检测、判决，以降低误判的概率。
