“In this paper, we propose a monostatic radar design for multitarget detection based on orthogonal-frequency division multiplexing, where the monostatic radar is co-located with the transmit antenna. The monostatic antenna has the perfect knowledge of the transmitted signal and listens to echoes coming from the reflection of fixed or moving targets. We estimate the target parameters, i.e., range and velocity, using a two-dimensional periodogram. By this setup we improve the periodogram estimation performance under the condition of low signal-to-noise ratio using Zadoff-Chu precoding and the discrete Fourier transform channel estimation.”
