Complete complementary sequence for MIMO radar waveform design with low range sidelobes

Doppler compensation method for the complementary phase‐coded signal

“…The wave length of the high‐frequency ground wave radar is so long that the Doppler frequency effect is too little to be ignored. In [3, 4], the application of complementary sequence in MIMO radar was presented as the ideal auto‐correlation and cross‐correlation properties, which can be utilised in MIMO radar systems to cancel the range sidelobe.…”

Designing Waveform Sets with Good Correlation and Stopband Properties for MIMO Radar via the Gradient-Based Method

“…In recent years, a large number of scholars has been devoted to designing waveform sets with a good correlation property. The main research covers two aspects: one is the waveform sets with good auto- and cross-correlation properties [9,10,11,12,13,14,15,16], and the other is the complementary sets of sequences (CSS) [17,18,19,20,21,22,23,24,25]. …”

“…In pulse compression radar, the complementary sequences are used to modulate consecutive pulses in a coherent pulse train. Then, the autocorrelation sidelobes can be reduced via the coherent [19] or noncoherent [18] accumulation, which can be regarded as the process of obtaining the autocorrelation sum of the complementary sequences. Moreover, due to the good correlation property, CSS has been widely applied to the CDMA system [21], ISI (intersymbol interference) channel estimation [22], orthogonal frequency division multiplexing (OFDM) [23], and many other areas.…”

“…CSS design is proposed to overcome the difficulty of generating a single unimodular waveform with ideal (impulse-like) autocorrelation. A common application of the CSS is the pulse compression [ 18 , 19 , 20 ]. In pulse compression radar, the complementary sequences are used to modulate consecutive pulses in a coherent pulse train.…”
