摘要： A system includes a processor and a non-transitory computer-readable medium storing machine instructions executable by the processor. The processor obtains an input radar signal, determines coefficients for an auto-regressive model based on the input signal and an order size, and extrapolates the input signal based on the model and the determined coefficients to obtain an extrapolated signal. In some implementations, the input signal comprises a number N of samples, and the order size is approximately half of N. The coefficients are determined based on the N samples, and the processor extrapolates a right-side signal based on the model, the determined coefficients, and a second half of the N samples; extrapolates a left-side signal based on the model, complex conjugates of the determined coefficients, and a first half of the N samples; and generates the extrapolated signal based on the left-side signal, the input signal, and the right-side signal.
