Pseudo-code for producing the cluttergram.
| Input: | Orbit→ nadir coords: (xc, yc), heights (ha, hb) |
|---|---|
| DTM→ (x, y, h) | |
| Step1: | Initial a cluttergram Pr(i, j) = 0, j ϵ (0,1,…, J), i ϵ (0,1,…, I) |
| Step2: | For jth nadir point, get (xc, yc, ha, hb) |
| Step3: | For jth nadir point, extract a DTM patch around it |
| Step4: | Foreach each element in the DTM, extract (xp, yp, hp) |
| calculate ip using Eq. (6) | |
| calculate Prk using Eqs. (8), (9) | |
| Step5: | Update the cluttergram pixel value with Pr(ip, j)+ = Prk |
| Step6: | Return to Step2 if j ≤ J |
| Output: | Cluttergram (i, j, Pr) |
