Design and Implementation of Signal Processing Algorithm for High Altitude Pulse Compression Radar Altimeter
A novel signal processing algorithm design for an intra-pulse LFM (linear frequency modulation) & inter-pulse PPM (pulse position modulation) compression radar altimeter is given. In order to enhance the performance of signal processing algorithm，a correlation integration algorithm based on mismatched code is provided. The corresponding flight verification test results in different terrain have been presented. Flight test shows that the signal processing algorithm of the high altitude pulse compression radar altimeter has very high processing gain and superior performance for weak echo signal detection.
