Abstract:
1. A method for measuring a radial velocity of a target with a radar, within a maximum range R max , comprising the steps of: transmitting an Orthogonal Frequency Division Multiplexing (OFDM) waveform p, the waveform comprising: N frequency carrier signals (p a plurality of OFDM chips and guard time intervals that are transmitted successively, on at least a portion of the N frequency carrier signals, to form a continuous wave transmission, wherein: recovering an initial phase φ cyclically shifting the recovered initial phase φ decoding the recovered and shifted initial phase φ synthesizing a compressed pulse from the plurality of decoded initial phases (φ wherein the step of recovering the initial phase φ wherein the step of cyclically shifting the recovered initial phase φ wherein the step of decoding the recovered and shifted initial phase φ wherein the step of synthesizing the compressed pulse from the plurality of decoded initial phases further comprises multiplying the plurality of decoded initial phases by a matrix ℑ wherein the recovered initial phases φ
