E-190
E-190 is operating in the X-band airborne weather radar.
The scanner unit was a 2 axis scanner with line of sight stabilization. The reflector antenna had a standard size of 24 inches (≙ 61 cm). It scanned over the range ± 90° in azimuth at 40 scans (20 cycles) per minute.
The E-190 was introduced at the 1959 Farnborough Air Show and remained in service for over 50 years.
