Example Embodiment
[0042] Based on waveform agility space-based radar target and clutter range defuzzification methods, such as figure 1 .
[0043] Step 1: Calculate the shortest distance Rmin and the longest distance Rmax of the radar beam coverage area according to the orbit height H, the earth radius as R, the radar elevation beam width θ, and the downward angle of view of the radar beam center as α:
[0044]
[0045]
[0046] Step 2 Assuming that the radar system intends to use the pulse repetition frequency as PRF, calculate the number of ambiguities of the main lobe N, it is easy to know that N is greater than The smallest integer of , at this time, there are N ambiguity regions in the radar range. .
[0047] Step 3 The radar transmits N radar signals S with the same bandwidth and orthogonal waveforms i (t), i=1,2,...,N,
[0048] where ∫S i (t) * S j (t) * dt=0, i≠j.
[0049] Step 4 Assuming that the radar transmits M pulses in one coherent accumulation time, and then receive...
