Compressed sensing radar - new concepts of incoherent continuous wave transmissions

The most of the conventional SAR, ISAR or other kind of high resolution radars are today based on Linear Frequency Modulation (LFM) transmissions, where the range resolution is directly proportional to the used radio-frequency band and the pulse compression procedure is based on the Matched Filter (MF) theory. This traditional approach can be highly limited to the transmitted signal bandwidth, today extremely dependent on the electromagnetic spectrum availability. This paper demonstrates that incoherent transmissions can be focused using the CS reconstruction theory, erasing the need of a pulse compression stage, based on MF, and a required receiver analog-to-digital conversion bandwidth reduction. These kind of transmissions can be useful for anti-jamming transmissions, needing lower power, if compared between conventional based high resolution radars.
