Abstract: A digitally-controlled pulse shaper (DCPS) is provided which precisely controls the shape of the leading and trailing edges of a transmit pulse in a radar wind profiler, or pulsed-radar. In the case of pulse coding, where phase transitions are used to segment an otherwise longer pulse, the intra-pulse phase transitions are also shaped.

Abstract: A system of atmospheric remote sensing instruments that utilize a common phased-array acoustic antenna so as to take temperature and wind measurements over a wide range of altitudes. One of the atmospheric remote sensing instruments in the system is a monostatic SODAR that takes wind measurements by transmitting pulses of acoustic energy into the atmosphere and then measuring received reflected acoustic energy. The acoustic pulses are both transmitted and received by the common phased-array acoustic antenna. Another of the atmospheric remote sensing instruments in the system is a wind profiling radar that takes wind measurements by transmitting pulses of electromagnetic energy into the atmosphere and then measuring received backscattered electromagnetic energy. The pulses of electromagnetic energy are both transmitted and received by a phased-array radar antenna.

Abstract: A sound detection and ranging (SODAR) system for taking wind measurements by sending out acoustic pulses and then measuring acoustic energy reflected back to the instrument by the atmosphere. The acoustic pulses are formed using digital beamforming technology which allows the acoustic pulses to be steered independent of frequency due to a time delay design. Also, the present invention SODAR instrument allows wideband capability that is limited only by the dimensions of the antenna array. Furthermore, the present invention SODAR instrument allows the acoustic pulses to be variably steered and allows multiple acoustic beams to be simultaneously received.
