Characteristics and Detection of Moving Target Signal of Radar System Based on External Radiation Source
摘要
Abstract
Shortwave external radiation source radar system,which adopts AM radio as the signal source,needs a long time for signal accumulation to detect the weak target signal.The movement of the tar-gets will expand Doppler frequency,so the performance of traditional accumulation detection method will drop.An accumulation detection method based on target movement compensation is presented to solve this problem.The echo model of moving targets is described.The polynomial fitting accumulation detection algo-rithm principle is introduced.The compensation via simulation data and test data is made to verify the benefit of signal noise ratio before and after compensation target movement.Computer simulation is made to verify the detection performance of the accumulation detection algorithm.The computational load of the target movement compensation method is also evaluated.关键词
