Development of solid-state weather radar

Abstract

Today, amid mounting sense of crisis of concentrated heavy rains, weather radars are of growing importance in weather observation and prediction by virtue of their capability of rain-fall measurement over the wide area in a short period of time. Meanwhile, because of the limitation of bandwidth availability with increasing use of radio wave frequency resources, steady demand for weather radar is also expected. Moreover, there is strong demand for decreasing the running cost of weather radar. Toshiba has developed 5GHz and 9GHz solid-state weather radar, complying with the demand the best use of our world-leading microwave transistor technology and radar data processing technology. The radar has attained the specified level of spurious radiation suppression without sacrificing any of radar system performances. Toshiba intends to promote the sales of the solid-state weather radar.
