Indian MST radar 1. System description and sample vector wind measurements in ST mode

An MST radar operating at 53 MHz with an average power aperture product of 7 × 10⁸ W m² has been established at Gadanki (13.5° N, 79.2° E), India. The radar development has been accomplished in two phases. In the first phase it was commissioned in ST mode using a partial system comprising one quarter (16 × 16)of the Yagi antenna array and 16 driver units of the transmitters providing an average power aperture product of 4.8 × 10⁶ W m². In this part we present the radar system description, including off-line data processing, and some sample high-resolution vector wind measurements made in ST mode operation.
