Nonuniformly Spaced Array with the Direct Data Domain Method for 2D Angle-of-Arrival Measurement in Electronic Support Measures Application from 6 to 18 GHz

Figure 22

The comparison between the values of the first term (blue oooo) and the imaginary part of the second term (red ) of (D.2) with SNR = , when the frequency is at 10 GHz, the incident direction is from (143.75° 84.66°) to Array-3, the waveform is WF-1, and the number of snapshots is 512. Blue plus signs are the real part of the second term in (D.2). (a) Freq = 6 GHz; (b) Freq = 8 GHz; (c) Freq = 10 GHz; (d) Freq = 14 GHz; (e) Freq = 16 GHz; (f) Freq = 18 GHz.
