An S-band linear FM chirp signal generator, utilizing a backward wave oscillator BWO and a solid-state BWO modulator-driver circuit, was developed as part of an experimental high-range-resolution radar. The modulator-driven BWO was found to have a 3.5 to 2.9 GHz linear sweep with a 600-MHz bandwidth a 0.300 microsecond pulsewidth and a pulse compression ratio or time-bandwidth product of 180. In addition, it has the capability of operating to a maximum prf of 25 kHz without distortion of the chirp signal, and its maximum deviation from linear FM is less than 0.07 percent. Author
