Power budget design for an L-band radar with the following detection requirements: RCS = 1 m², range = 2,000 km, and SNR = 12.6 dB

Parameters	Relative Gain[dB]	Remarks
Transmit Power, Pt	7	Pt= 500 kW with P0= 100 kW,
Transmit antenna Gain, Gt	0	Gt= 40 dB @N = 5,000
Receive antenna Gain, Gr	3	N = 10,000, separate Rx antenna
Signal Processing Gain, Gp	13.3	64 pulse Integration (noncoherent)
Pulse width Control	3	Average power is increase by 2 ms
SNR Margins	10	Taking into account unmodeled losses
Total Increases	26.3	Pd= 80 %, Pfa= 10-6
