The Optimization Problems of Transmit and Receive Design for Radar Operating in Littoral Zones

Algorithm 1

Clutter spikes selection algorithm (CSSA).

Input: 𝑖 the index of the CUT.

Output: 𝑄_𝑟 the spike descriptor set;

Begin:

Estimation: estimate the SDs of the spikes and construct the descriptor set 𝑄_𝑟;

Version I: A threshold 𝜂 is used to determine whether a range cell contains a clutter spike:

Selection: 𝑄_𝑟 = select * from  𝑄_𝑟  where  𝜎²>𝜂;

Version II: The total number 𝑀 of the suppressed range cell is fixed:

Selection: 𝑄_𝑟 = select top  𝑀  * from  𝑄_𝑟  ordered by  𝜎  descending;

End.
