一种径向匀加速目标包络徙动补偿新方法
A New Method for Envelope Migration Correction of Target with Radial Acceleration
摘要
Abstract
The improvement of radar detection performance is commonly realized by the way of multi-pulses long-term accumulation. However, when the radar detects high-speed targets, there will be a secondary range walk caused by radial acceleration, which makes the radar detection performance degrade greatly. To solve this problem, a novel method to eliminate the secondary range walk suggested. First, we employ generalized second order Keystone transform on the echo signal. Then the high order of Doppler frequency is compensated by dechirping. At last, the generalized second order Keystone transform is again used to eliminate the secondary range walk completely. Computer simulation results confirm the effectiveness of the proposed method.关键词
