This article presents a methodology based on matched-adaptive filters, which is used to mitigate the effect of near-range multipath in multistatic SAR systems and transponders. It is challenging to physically construct a bistatic receiver such that t

The article proposes a methodology to perform azimuth focusing of spaceborne transmitter-stationary receiver bistatic synthetic aperture radar data across multiple along-track apertures to increase azimuth resolution. The procedure uses as input seve

In this letter, we present a low-complexity push–push voltage-controlled oscillator (VCO) that achieves over 17% highly linear MHz/V tunable bandwidth. Unlike traditional VCOs, the proposed design does not require dedicated voltage-sensitive reacta

Bistatic radar receivers that use an opportunistic transmitter require a reference channel to capture the original transmitted signal, which is then used as a reference signal for constructing the matched-filter during the range compression step. Bec
