High-Performance Advanced Receiver Processor (HARP)
Project Description
We are researching and developing a laser altimeter receiver. This receiver will employ multiple shot coincidence detection to maximize ranging capability with minimal laser-aperture size product and hence the cost. The proposed approach will increase the sensitivity of our receivers by a factor of 2. Advanced, high-performance, compact, low-power, on-board processor that increases the sensitivity of the receiver for laser altimetry and similar applications.
The pulse handling, and histogram and analysis functions are implemented in hardware at a high noise rate. Operation: a very large range gate is used to virtually eliminate tracking. At the end of a time period the histogram of the event times is analyzed, the range gate is determined with "20-20 hindsight," and select data is telemetered to the ground.
