摘要
连续波雷达与脉冲雷达相比较有诸多的技术和战术优点,但由于连续波雷达存在严重的发射直波泄露信号,给连续波雷达的广泛应用设置了技术瓶颈。本文全面介绍了连续波雷达发射直波泄露信号抑制技术,并对连续波雷达检测能力进行了分析,给出了连续波雷达不仅要求对发射直波泄露信号具有良好的抑制,同时还要求发射信号必须具备低(超低)相位噪声指标要求及其运算公式。
The continuous-wave ( CW) radar possesses many advantages in technology and tactics comparing with the pulsed radar, but a technological bottleneck for wide application of CW radar is set because it has serious leak-age of transmitting direct wave signal. The CW radar transmitting direct wave signal leakage suppression technology are introducd completely;the CW radar detecting capability is analyzed;and requirement for CW radar not only to suppress transmitting direct wave leakage signal well, but also its transmitting signal must have low ( ultra-low ) phase noise specifications for the CW radar and its operation formulas are given.
