The operation of a system for directional scanning of the ionosphere using a steerable (phased) antenna array is described. The antenna array was used in conjunction with digital techniques and conventional pulse sounding to investigate structures in the normal E-region near 100 km altitude. The experimental hardware included a 1 km cross-array, transmitting approximately Gaussian pulses of half power width of about 30 microns at repetition rates of 100 or 200/sec and a frequency of 1.98 MHz. The total radiated power was 32 kW from linear dipoles. Data from the lower E-region during disturbed periods indicated the presence of a few simultaneous reflections from different directions, each lasting only several seconds. The theory that the fading of E-layer echoes is due to interference between a small number of discrete reflectors is in agreement with observations by Felgate and Golley (1971). There is also evidence that disturbances lasting several minutes occur.
