Abstract :
The CASA NSF ERC is using cutting edge radar technology to create a network of short range weather radar to observe the lower regions of the atmosphere that are currently out of sight. Range oversampling and whitening is one of the newest technologies available for increasing the accuracy of weather radar moment estimates. The CASA mission has incorporated range oversampling into the design of one the first prototype radars created for the mission. Due to several constraints, the MA-1 radar has several hardware design differences from the large state-of-the-art S-band weather radars that oversampling and whitening was developed and verified with. The oversampling and whitening process is validated with the suboptimal MA-1 radar configuration by producing results that adhere to theoretical expectations.
