Embodiment Construction
[0031] refer to figure 1 , is a flow chart of a registration-based airborne forward-looking array radar clutter suppression method of the present invention; the registration-based airborne forward-looking array radar clutter suppression method comprises the following steps:
[0032] Step 1. Determine the airborne forward-looking array radar. There is a clutter scatterer S within the detection range of the airborne forward-looking array radar. Airborne forward-looking array radar unwanted echo objects.
[0033] The airborne forward-looking array radar transmits signals and receives radar echo data, and the radar echo data contains N max The radar echo data of the range gates are sequentially recorded as the radar echo data of the first range gate, the radar echo data of the second range gate, ..., the Nth max The radar echo data of each range gate; record the radar echo data of each range gate as a unit data to be detected, and then get N max unit data to be tested.
