1. A multistatic radar system comprising: a transmitter for transmitting a first signal at a first time to reflect off a target, the first signal reflecting off the target as a second signal at a second time; a plurality of spatially separated receivers on corresponding geographically separated platforms, each of the receivers being configured to receive the second signal from the target as one of a corresponding plurality of third signals and at one of a corresponding plurality of third times; and a signal processor for fusing the third signals and the third times from the receivers, wherein the fusing of the third signals and the third times comprises: aligning the third signals in time delay and Doppler shift using the corresponding plurality of third times; and summing the resulting aligned third signals to detect or geolocate the target at the second time.
