ABSTRACT:
A low cost airborne weather radar system suitable for mounting in the wing of a single engine aircraft. The radar antenna is a truncated parabolic dish. The receiver/transmitter, relative to parameters used in a conventional receiver/transmitter operates at relatively small peak transmitter power with a relatively long transmitter pulsewidth which, in turn, is matched to the receiver bandwidth. The relatively small peak power allows for acceptable range performance due to the relatively larger pulse width. Further, the receiver/transmitter assembly is significantly reduced in size so as to facilitate location in an aircraft wing and be thereby directly connected to the antenna to eliminate range reducing intercabling losses.
