A procedure for the mapping of radar targets which are spread both in delay and frequency offset is described. The procedure is based on transmitted pulses with linearly chirped frequency variation. The reconstruction of the properties of the target scattering function is achieved by combining observations made with a large number of different chirp rates. The procedure is closely related to tomography methods employed in other observational contexts. The relationship between tomographic reconstruction and multiple chirp reconstruction is discussed. Possible applications of this reconstruction method exist in HF ionospheric modification experiments, in mesosphere-stratosphere-troposphere radar applications as well as in the radar astronomy of planetary bodies.
