However, reliable assessment remains difficult due to neck adiposity, anatomical variability and suboptimal positioning. Although central venous catheterization is the gold standard, its invasive nature restricts routine or long-term use. This study introduces a non-invasive method for JVP estimation using a 60 GHz frequency-modulated continuous wave (FMCW) radar. The system captures venous pulsations at the skin surface and applies eigenbeamforming to enhance signal-to-noise ratio and pulse clarity. Radar parameters were optimized for signal fidelity and validated through morphological comparison with simultaneously recorded photoplethysmography (PPG) signals. Additionally, we compared radar-derived JVP signals with previously recorded catheterization data from a patient with early-stage heart failure to assess clinical relevance. Signal localization was successfully achieved within a direction-of-arrival (DoA) range of\n                    <jats:inline-formula id=\"ui1\">\n                      <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" display=\"inline\" id=\"u1\" overflow=\"scroll\">\n                        <mml:mrow>\n                          <mml:mo>\u2212<\/mml:mo>\n                        <\/mml:mrow>\n                        <mml:mrow>\n                          <mml:msup>\n                            <mml:mn>20<\/mml:mn>\n                            <mml:mo lspace=\"0em\" rspace=\"0em\">\u2218<\/mml:mo>\n                          <\/mml:msup>\n                        <\/mml:mrow>\n                      <\/mml:math>\n                    <\/jats:inline-formula>\n                    to\n                    <jats:inline-formula id=\"ui2\">\n                      <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" display=\"inline\" id=\"u2\" overflow=\"scroll\">\n                        <mml:mrow>\n                          <mml:mo>+<\/mml:mo>\n                        <\/mml:mrow>\n                        <mml:mrow>\n                          <mml:msup>\n                            <mml:mn>20<\/mml:mn>\n                            <mml:mo lspace=\"0em\" rspace=\"0em\">\u2218<\/mml:mo>\n                          <\/mml:msup>\n                        <\/mml:mrow>\n                      <\/mml:math>\n                    <\/jats:inline-formula>\n                    , demonstrating the radar\u2019s precision.
