混沌调频信号类似随机信号，具有较强的抗干扰性能(ECCM)。

Chaotic FM signal is similar to random signal. It has good Electronic Counter-Counter Measure (ECCM) capabilities.

调频差分混沌键控(FM -DCSK)的比特能量是常数，可以提高传输速率，但和CS K相比较，性能上仍有差距。

The energy per bit of FM-DCSK is kept constant to increase the transmission rate. But the performance of CSK is yet better than that of FM-DCSK.
