A prototype single‐pulse ionospheric sounding system has been devised at the Radio Physics Laboratory of Stanford Research Institute. The sounding system was installed and operated at a field site near Menlo Park, California, between July 1968 and January 1969. From a single transmitted RF pulse, it has been possible to obtain a vertical‐incidence ionogram over a frequency range exceeding 7 MHz. In addition, the very narrow (nominally 1 μsec) transmitted pulse of the system has permitted the detection and identification of E ‐region echoes <600 meters thick, a determination not possible with conventional sounders.
