“…Expanding the PTRS as a Taylor series with respect to the instantaneous frequency, various imaging algorithms are developed. The second order series approximation is exploited by the range-Doppler (R-D) algorithm [24] and chirp scaling (CS) algorithm [25]. The nonlinear CS algorithm [26,27] and quartic phase algorithm [28] are based on the third and fourth order approximation, respectively.…”

“…By exploiting the coherent processing of consecutive displaced echo data, SAS can produce high performance image [1–6]. This technique uses the movement of the sonar sensors to synthesise a large virtual array, which is greatly different from traditional static large array of transducers.…”
