The performance of Space-Based Radars (SBR) orbiting on elliptical orbits is discussed. Their ability to detect air-breathing targets is analyzed as a function of the antenna look angle, the orbital parameters of the satellite, the number of radio pulses transmitted and the peak power of the radar. The results show that the minimum detectable velocities of the SBR tend to degrade as the satellite approaches the apogee of its orbit. Depending on the orbital parameters of the satellite, the advantage of more extended coverage when the satellite is at the apogee of its orbit could be hindered by the poorer performance of the radar.
