This unknown radar has been observed on the lower HFHigh Frequency (3-30 MHz) band. It transmits in pulses and changes frequency on each pulse. This behavior is similar to CODAR but this radar does the sweep much faster (15.6 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). rate) than CODAR and pulse rate is lower (125 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz).) than that of typical CODAR. Bandwidth is 20 kHzKiloHertz (kHz) 10^3 Hz or slightly more.
