Title: Radar modulation for ambiguity reduction in pulsed radar
IPC: G01S13/50
Filed: 1974-02-25
Abstract: 1404926 Radar MOTOROLA Inc 25 Feb 1974 [12 March 1973] 8391/74 Heading H4D A radar using a standard pulsed signal transmission has an ambiguity diagram, Fig. 3 exhibiting a plurality of peaks 36, 38, 40 along the time axis 28 giving rise to range ambiguities and a plurality of peaks along the frequency axis 30 giving rise to velocity ambiguities. A linear frequency modulated CW signal, having a deviation equal to a multiple, e.g. 1, of the PRF of the pulse signal has a series of peaks along the time axis 272, Fig. 10, of the ambiguity diagram with nulls coincident with the peaks of the pulse signal ambiguity diagram. It is stated that a pulse signal transmission wherein the carrier frequency of the pulses varies from pulse to pulse according to a linear sweep with a deviation equal to the pulse's PRF gives an ambiguity diagram obtained by multiplying together the two ambiguity diagrams of the two different kinds of transmission, i.e. a single peak at the origin of the time and frequency axis, or the ambiguity diagram of Fig 3 rotated about the amplitude axis 32 until the peaks 36, 38, 40 are no longer on the time axis. To produce the desired signal transmission, the 25À6 MHz output of a high stability oscillator 68, Fig. 5, is fed to flip-flops 86, 114 and to a "by-32" divider 72. The output A, Fig. 6, of divider 72 is at 800 KHz but has leading edge jitter, this is removed by flip-flop 86 using the output of the oscillator 68 as a stabilizer. The output A is fed to a PRF output 64. A "by-64" divider 108 receives the output A to produce a jittery signal which is stabilized by flip-flops 114 to give a sweep period signal E. The stablized PRF signal B causes a monostable circuit 90 to produce gating pulses 100 for a 30 MHz oscillator 96, 102, 104. The pulses (coherent from pulse to pulse) of 30 MHz radiation are fed to one input of a mixer 108. The sweep period signal E is converted to a reset signal F at 120 for causing the charge and linear discharge of a capacitor 152. This produces a ramp signal G linearly varying the output of an oscillator 134 from 314À6 MHz to 315À4 MHz over the sweep period, i.e. 64 times the PRP and with a sweep of 800 KHz equal to the P.R.F. This signal is fed to the record input of the mixer to give the pulsed signal with carrier waves linearly varying from 344À6 MHz to 345À4 MHz. The arrangement 60 of Fig. 5 is incorporated as a modulation code generator in the radio transmitter/receiver of Fig. 9 wherein the pulsed signal is shifted up in frequency by 10 GHz before transmission, and the echo signals are subjected to two stages of coherent detection (240, 252) before application to processing circuitry 260, 261, 262.
