ABSTRACT:
A multiple frequency laser technique for enhancing the detection of discrete targets amid a clutter background while also increasing the range performance or power limits of the laser type radar. Each of a plurality of laser oscillators cooperates by heterodyned phase-lock means to provide a mutually exclusive one of a plurality of mutually coherent frequencies, whereby the transmitted continuous wave energy comprises a coherent pulse train.
