A radar system operating by the line-of-sight method requires an accurate measurement of the relative position of at least two objects. By sending out coded radar transmission pulses, control data are transmitted to a guided flying body in a radar beam, which sends back an echo signal to the receiver via a transponder. In order to measure the passive signal and the transponder echo signal in the radar beam as accurately as possible, common reception channels are provided for both echo signals containing, inter alia, arrangements to equalize the dynamic levels of the echo signals. The returned transponder echo signal corresponds with respect to coding and bandwidth to the transmission pulses originally generated in the transmitter and that are phase-coded but not provided with the control code.

A radar system for determining the position of at least two objects, including a first, guided object and a second, target object, said radar system having a transmitter for transmitting pulse transmission signals and a receiver for receiving echo signals from said guided and target objects, wherein the transmitter sends control data to said guided object, by utilizing a control code impressed on a phase-coded pulse transmission, wherein said guided object sends a transponder echo signal back via a transponder to the receiver, said receiver including a microwave network on its input side, said microwave network being coupled by a plurality of reception signal processing channels to a mixing and preamplifying arrangement, characterized in that the same ones of said reception channels are provided in said receiver for both a passive echo signal that is a reflection of a pulse transmission signal from said target object and said transponder echo signal and in that said transponder provides said transponder echo signal similar with respect to coding and bandwidth to said pulse transmission originally sent by said transmitter and said transponder echo signal is phase-coded but not provided with said control code, and wherein the received echo signals are correlated in said receiver with a phase coded signal similar to said pulse transmission originally sent by said transmitter.
