ABSTRACT OF THE DISCLOSURE A system for transmitting a comb of radar signals. The invention includes a phase shifter for shifting the phase of an input carrier signal. A frequency modulation signal is adjusted in amplitude by an attenuator 16 and input to a balanced mixer 14. The balanced mixer 14 mixes the input carrier signal with the attenuated frequency modulation signal. A summer 20 combines the output of the phase shifter 12 with the output of the balanced mixer 14. The system 10 of the present invention provides an inexpensive means of generating and receiving a complex of illuminating signals having a spread spectrum consisting of lines (teeth) of carrier frequencies with controllable power. The system 10 is agile in that the power levels and the spectral positions of the teeth may be varied.
