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. 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 = .
