For　a　noncooperative　target,　multiple-dimension　detection　is　required　to　determine　its　spatial　location.　A　microwave　photonic　radar　is　proposed　for　simultaneous　detection　of　the　distance　and　direction　of　targets.　At　the　transmitter,　a　linear　frequency　modulation　(LFM)　signal　with　a　large　instantaneous　bandwidth　was　obtained　by　frequency　doubling.　Meanwhile,　the　optical　reference　signal　was　supplied.　At　the　receiver,　two　antennas　with　a　certain　baseline　length　were　used　to　receive　the　echo　signal.　The　dechirp　process　and　fixed-length　cable　are　combined　to　decouple　the　distance　and　direction　and　distinguish　between　the　positive　and　negative　directions　of　a　target.　Theoretical　derivation　has　already　verified　that　the　distance　and　direction　can　be　resolved　simultaneously　by　dechirping　of　the　echo　modulation　signal　and　reference　signal.　In　experiments,　an　LFM　signal　with　an　instantaneous　bandwidth　of　2　GHz　(2-4　GHz)　was　generated　and　launched　as　the　detection　signal.　Targets　at　different　distances　with　positive　and　negative　angles　were　detected.　The　results　show　that　the　directional　measurement　ranges　from　-72.5　0　to　72.5　degrees,　and　the　error　is　less　than　1.6　degrees.　The　measured　distance　was　found　to　be　quite　similar　to　the　actual　distance.　The　proposed　approach　can　confirm　the　spatial　location　of　a　noncooperative　target　by　combining　the　detection　of　both　distance　and　direction.　Furthermore,　the　baseline　length　need　not　be　less　than　half　the　wavelength　of　the　echo　signal,　and　large　antennas　can　be　chosen　to　improve　the　detection　distance　and　range　accuracy.　(C)　2021　Optical　Society　of　America　under　the　terms　of　the　OSA　Open　Access　Publishing　Agreement
