The detector η ( m ) of multicomponent LFM signal with T = 40 s and different parameters. (a) The η(m) of the bicomponent LFM signal with amplitude of one component being one tenth of other. $(a,b,c,d)=(1/32,16,-1/32,16),w_0=w_1=0.1\text{rad}/s,m_0=0.4\text{rad}/s^2,m_1=$0.2 rad/^{s 2}. (b) The η(m) of three-component signal with different amplitude. (a,b,c,d) = (1/32,32,−1/64,16), w₀ = w₁ = w₂ = 0.1 rad/s, m₀ = $0.2\text{rad}/s^2,m_1=0.4\text{rad}/s^2,m_2=0.6\text{rad}/s^2$.
