Optimal ambiguity function radar

摘要: This radar incorporates a single channel, two-dimensional correlator, providing simultaneous correlation in the range/doppler plane. In conventional processors, separate channels are used to measure range and doppler. Range track is normally established first signal then enable, or correlate with doppler channel. this invention, performed simultaneously channel truly represents combined ambiguity function, rather than an attempt merge two functions. A purely random sequence of binary bits (+1 -1's) control phase each segment transmitted (either pulse CW) as opposed systems using pseudo-random sequences generated by various means such linear shift register generators. digital number generator produce set numbers which, when applied rule, generates bits, plus minus 1's (±1's), which bi-phase modulate carrier frequency. The rule is: if n(i)≧0.5, p=1; n(i)<0.5, p=-1; p=a + -1's (ones). resulting modulated amplified sent transmit antenna.
