  We present a novel scheme allowing for 2D target localization using highly
quantized 1-bit measurements from a Frequency Modulated Continuous Wave (FMCW)
radar with two receiving antennas. Quantization of radar signals introduces
localization artifacts, we remove this limitation by inserting a dithering on
the unquantized observations. We then adapt the projected back projection
algorithm to estimate both the range and angle of targets from the dithered
quantized radar observations, with provably decaying reconstruction error when
the number of observations increases. Simulations are performed to highlight
the accuracy of the dithered scheme in noiseless conditions when compared to
the non-dithered and full 32-bit resolution under severe bit-rate reduction.
Finally, measurements are performed using a radar sensor to demonstrate the
effectiveness and performances of the proposed quantized dithered scheme in
real conditions.
