The Multi-Channel, Multi-Mode Receiver (MCMM-RX) system is a four channels wide bandwidth radio receiver using a Innovative Integration X5 210M card in a industrial or compact PCI computer.  Custom logic is implemented in the Virtex5 SX95T for the signal processing and data flow controls.  Inputs to the system are four analog inputs and sample rate clocks upto 180 MHz into four receive channels.  Each channel has independent software defined tuner and baseband demodulation.  Demodulation module includes BPSK, QPSK, pi/4 QPSK, and 8PSK.  MCMM-RX can be integrated into a PC architecture computer system with data recording capability using RAID array or hard disks.

This proposal describes the development of a high speed 2 GSPS waveform digitizing, analysis, and recording system for a LIDAR system. The result of development described in this proposal is a LIDAR receiver on a single electronics module able to identify up to 16 targets for a pulse repetition period from 10us to 100us. The receiver reports the time, dispersion, and amplitude of each echo pulse, and maximum pulse amplitude in each return relating to the target distance and composition. Significant developments include signal processing firmware for analyzing the LIDAR pulse in real-time. The signal processing method as outlined in this proposal, enables the LIDAR receiver functionality in the digitizer hardware as firmware.
