Abstract

Radar design is subject to trade-offs between maximal range, maximal unambiguous Doppler and range resolution. This work proposes to break these limiting trade-offs by extending the pass band of the anti-aliasing low pass filter (LPF). This enables extended range detection, but introduces aliasing in range. We propose a multi sampling rate receiver approach which enables this extension by mitigating the aliasing, without compromising Doppler ambiguity and range resolution. Straightforward multi-rate sampling compromises coherency between the receive channels, and therefore, a novel approach to re-gain this coherency is derived. The performance of the proposed approach is demonstrated using measurements collected with a 77GHz automotive radar.
