[0037] The present invention will be further explained below in conjunction with the drawings:
[0038] Reference figure 1 , Is a schematic flowchart of a post-Doppler optimal clutter suppression method for reconstructing a reference channel of the present invention. The post-Doppler optimal clutter suppression method for reconstructing the reference channel includes the following steps:
[0039] S1: Use the airborne early warning radar to receive the echo data. The echo data received by the airborne early warning radar includes the first range unit to the Q-th range unit, and Q is a natural number greater than 1. The airborne early warning radar receives echo pulse data (raw data) corresponding to each range unit through multiple receiving channels, and preprocesses the echo pulse data received by each receiving channel. Preprocessing the echo pulse data received by each receiving channel includes: sequentially performing distance compression, quadratic term compensation, and Do...
